Marcus Smart shocked the college basketball world this past offseason when he decided to put the NBA on hold for another year, but he’s the exception -- and not the rule.

That’s why I’m assuming that surefire lottery picks such as Kansas' duo of Joel Embiid and Andrew Wiggins, Duke’s Jabari Parker, Kentucky’s Julius Randle and Arizona’s Aaron Gordon are history after just one season in the college ranks. Smart, Arizona State's Jahii Carson and UCLA's Kyle Anderson already have said they will be gone after this year as well.

But here are 15 players with deep-impact decisions, guys who could completely alter not only the look and feel of their own program -- but also the college basketball landscape in 2014-15.

Nik Stauskas, Michigan Wolverines

NBA folks I’ve talked to have the 6-foot-5 and change Canadian wing as a guy who will likely be taken somewhere in the 10-20 range. Stauskas has expanded his game and shown he can do more than just shoot the ball. He's athletic and has a tremendous feel for the game. John Beilein has three players who could all decide to leave -- Stauskas, Glenn Robinson III and Mitch McGary. If somehow all three returned, the Wolverines -- with freshman point guard Derrick Walton Jr. having a year under his belt -- could have a chance to challenge for the national title next season.

Tyler Ennis, Syracuse Orange

He has come out of nowhere and is now considered a lock first-rounder -- and possibly even a lottery pick.
