It’s been nearly five months since this happened. And then this. And then this. Oh, we can’t forget about that. Or this (unverified rumor, to be clear). And of course this.

Yep, a strange few months for Dustin Johnson and golf.

That initial period of hectic rumor-mongering is over though, and the American’s stay on his leave of absence (or whatever you believe it to be) is nearing its conclusion.

How do we unravel this power-hitting puzzle? Here is a breakdown of the most tantalizing questions about Johnson, maybe golf’s greatest enigma, heading into 2015.

When will Johnson return to competition?

For those of you who haven’t followed the 30-year-old’s whereabouts following his shocking July announcement, Tim Rosaforte has provided us the answer…or at least a well-educated guess.

The veteran golf scribe spoke with members of Johnson’s team (manager, coach and trainer) and was able to obtain that the American is planning to return to golf tentatively at the Farmers Insurance Open, which starts Feb. 5.

Tentative is the operative word. Schedules can change, and these reports also state Johnson iterating that he will wait until his fiance Paulina Gretzky gives birth to the couples’ first child before he competes again. We do not know the due date, so his return date could easily be pushed back.

When he returns, how will Johnson address the questions about his sabbatical?

Johnson has never been an expansive guy in interviews, and there’s nothing wrong with that, especially in today’s hypersensitive media age. Those are just the facts.

I assume he will start out with a statement of his own, and when it comes to media questions, I expect vague answers. Of course, he will likely get direct questions about whether he was suspended, prior drug use, etc.

Before Johnson’s leave of absence, his agent had once answered questions about whether his client had ever been suspended by the PGA Tour with a swift “no.”  That response hasn’t changed, nor will it to queries on any of the topics in question.

If you expect real, meaty answers here, disappointment will ensue.

Will the players welcome him back?

Gary Van Sickle already covered this one, and I agree with his assessment. There have never been any reports of players disliking Johnson, and the PGA Tour pros tend not to be too judgmental about a colleague’s problems. I’m doubtful Johnson will receive many cold shoulders in his return.

Does Johnson appear ready to return to competition?

Well, he’s keeping his whereabouts a secret, and is by proxy seen by few people. Because of that, our only source material here is the members of team Johnson that I noted above. Clearly this is a biased group whose encouraging words must be taken with several grains of salt.

That being said, even adjusting for this healthy skepticism, the reports on Johnson’s offseason are positive.

Apparently he put up his sticks for eight weeks and then furiously got to work. According to his people, Johnson is committing to his physique like never before, completing a heavy amount of biking along with strenuous two-a-day workouts. And his practice sessions have been quite focused and pristine as well.

His course-record-setting round of 61 at Sherwood Country Club, if true, is a good touch, too. Butch Harmon, who once called out Johnson as a guy who was outworked by everybody else in the top 10, says he’s cautiously optimistic about Johnson.

Trust what you want to trust, but it doesn’t appear Johnson is lollygagging in his absence.

If Johnson slips up significantly in 2015, will sponsors treat him like a landmine as they did for Tiger in 2010?

If you remember, the 2010 season wasn’t a fond one for Woods. Three sponsors — Gatorade, Accenture and AT&T — kicked him to the curb outright within months of the scandal’s beginning. Three more would drop or mutually split with Woods by the end of 2011.

But the circumstances around Woods were just too singular for Johnson to be hit with the same exodus.

That being said, I’d keep an eye on Johnson and TaylorMade.

The two have been together since the American’s pro debut, but company CEO Ben Sharpe admitted last month that TaylorMade and Johnson have had exactly zero contact since the news of Johnson’s “leave of absence” broke.

Sharpe’s quotes don’t convey any annoyance, but being mum with a long-term main sponsor that stood by you in turbulent times isn’t exactly a recipe for a satisfied employer.

TaylorMade’s contract with Johnson ends at the close of 2015. With the deadline looming so near, wouldn’t a particularly poor on-course season or a clear lack of personal growth from Johnson at least tempt the equipment giant into axing its long-bombing bad boy?

I’m not saying a split here is probable or even that likely. It’s just something to think about considering the context of Johnson’s absence, his lack of communication and the specter of his expiring contract.

What should we expect from Johnson on-course in 2015?

Year-to-year, however, the 30-year-old is remarkably similar in performance. In his six full PGA Tour seasons following his rookie year, Johnson has averaged 1.1 wins, 6.7 top-10s and 10.2 top-25s per year, with a 82 percent made cut rate.

And basically every single year, his numbers cling close to those averages. His wins have fluctuated between 1 and 2 per season, his top-10s between 5 and 9, his top-25s between 8 and 12 and his made cut rate between 73 and 89 percent.

Those are remarkably small ranges.

My point? I know the story of a catastrophic downfall in performance or a rise to superstardom in the wake of scandal are sexy angles, but Johnson’s on-course results will probably fall somewhere in that mitigated range.

Yes, the scouting reports on Johnson’s offseason progress are excellent. But again, these comments come courtesy of a PR filter, and how often do you hear healthy athletes say, “Yeah, I only feel so-so about this upcoming season”?

On the other side, a long break from golf is least likely to hinder a guy like Johnson, a total feel player who already has one extended professional vacation on record (that 11-week hiatus in 2012).

Sorry to be boring here, but I expect a quintessential Dustin Johnson season in 2015.

Is This a Professional Crossroads Year for Dustin Johnson?

It’s tempting to label this season as one where the back half of Johnson’s career is firmly at stake, with any failures sabotaging a strong ending. His lack of major championships looms large, but remember: HE’S ONLY 30 YEARS OLD.

Although we can’t always accurately predict the effects of aging on any one golfer, the average pro tends to have a near decade of prime years from age 30 on. According to the norm, we are really at the front end of Johnson’s prime.

You can see why I’m skeptical about this “crossroads” thing then. A bad season for a 30-year-old is just that: A bad season. It’s difficult to envision a downward spiral when Johnson’s physical talent is near the peak and likely not set to decline for a couple of presidential election cycles.

Short of Johnson suddenly gaining 10 years in age in the next month, crossroads is an inaccurate way to describe his professional status in 2015.

Will Johnson finally win a major championship this season?

I actually like his odds here. As I already mentioned, I don’t think Johnson will really be hindered at all by his extended absence. His chances at a major won’t be dinged then by a drop in performance.

And the set of courses at the final three majors of 2015 suits him extremely well.

For the U.S. Open, Chambers Bay is expected to be a track with wide landing areas on the drive, and at 7,585 yards, it is a long one too. It seems that big hitters and great approach players, both of which describe Johnson, are especially encouraged to excel there. And those same profiles mesh with players most attractive to St. Andrews for the British Open and Whistling Straits for the PGA (if you don’t trust me, the 21st century major champion winners at these venues are Tiger Woods, Vijay Singh, Louis Oosthuizen and Martin Kaymer, all of whom fit the longer hitter-approach player profile).

The caveat for some is that a major championship is the next step in Johnson’s evolution as a golfer, and he isn’t ready for that leap. But we’re misplacing the “next step” concept. Not to diminish the difficulty of winning a major, but all that entails is getting hot at a big event with a great field. The 30-year-old already did that twice in the FedEx Cup Playoffs and another time in winning a World Golf Championships last year. He’s actually done it at majors too, with the victory crown barely eluding him. Those crunch time major championship moments are likely to turn in his favor at least once at some point.

Johnson’s real next step is consistently putting together multiple-win, double digit top-10 seasons. As lovely as it is to put up his current averages year-after-year, he seems to be stuck on those numbers.

All in all then, I’m optimistic that Johnson finally bags that elusive major in 2015. Such a victory doesn’t imply that his season will be above his norm or that the American has finally transformed into the golfer we believe his talent merits.

If he wins one of the Big Four, he remains the same old Dustin. And the old Dustin should triumph at a major in 2015.
