It’s been one of the bigger mysteries in college basketball the past few years, as the all-time winningest men's coach in Division I history approaches the twilight of his career. Who will replace Mike Krzyzewski in Durham? And, on a related note, who even wants to follow Coach K after what he has done with the Duke program?

Even the obvious names -- those who have spent time under Coach K -- are far from locks to be considered candidates. In part because it’s not exactly as if the Coach K coaching tree has torn it up over the years. Quin Snyder has revived his career as an NBA assistant after being forced to resign at Missouri for NCAA issues. David Henderson struggled in his head-coaching stint at Delaware. The same can be said for ex-Duke assistants Tim O’Toole (Fairfield) and Mike Dement (UNC Greensboro and SMU).

Johnny Dawkins finally got Stanford into the NCAA tourney this past season -- his sixth in Palo Alto -- but he entered 2013 with a lack of job security. Tommy Amaker struggled at Michigan but has become a hot commodity at Harvard, and guys such as Chris Collins and Steve Wojciechowski are early on in their head-coaching careers at Northwestern and Marquette, respectively. Where does that leave things?

Below, we handicap the current odds to be Coach K’s successor once the 67-year-old does decide to call it quits.

Tommy Amaker, Harvard Crimson

He certainly has made up significant ground over the past few years while building a powerhouse at Harvard.
