Willie Cauley-Stein, Kentucky
Cauley-Stein missed Kentucky's final three games last season thanks to an ankle injury that eventually required surgery. He isn't playing in Kentucky's current Bahamas Tour, but he hopes to be back for the start of the season.
Though he might be the most talented player on this entire list, the Wildcats have so much depth in the frontcourt that they'll be ranked No. 1 in the preseason with or without him.
DaJuan Coleman, Syracuse
If Coleman plays, it's a huge plus for Jim Boeheim and Syracuse. However, he only gets an honorable mention because it's the biggest "If" on the list.
In January, Coleman had surgery on his left knee for the second time in as many seasons. We'll give the benefit of the doubt after one surgery, but two is when we start to wonder if the player will ever be physically or mentally at 100 percent again.
Anthony Collins, South Florida
Collins had an inflamed bursa sac surgically removed from his left knee last summer.
He missed the first two games of the 2013-14 season but played in the next eight before tendinitis in the same knee eventually caused him to sit out the rest of the year.
Opposite of Kentucky's situation with Cauley-Stein, South Florida isn't going anywhere this season with or without Collins.
Kyle Collinsworth, BYU
Collinsworth had surgery for a torn ACL in mid-March. His goal is to be ready for the start of the season, but eight months to recover from a serious knee injury doesn't seem like quite enough.
If he does play, his 14.0 PPG, 8.1 RPG, 4.6 APG and 1.7 SPG from last season will be very much welcomed into a rotation that lost a number of key players due to transfer or LDS missions.
Kris Dunn, Providence
Dunn was one of the top incoming point guards in the entire country before the 2012-13 season, but multiple injuries to his right shoulder have kept him from ever truly getting the chance to shine.
He managed to appear in just four games last season.
Dunn should be back as the starting point guard for a team looking to remain competitive after losing two key seniors in Bryce Cotton and Kadeem Batts.
Kethan Savage, George Washington
Savage was one of George Washington's most important players before a foot fracture derailed his season. And with Isaiah Armwood and Maurice Creek graduating this summer, there's no question he'll be expected to be the team's leader for the 2014-15 campaign.
Kenyatta Smith, Harvard
Smith missed the first 17 games of last season with a foot injury. He played for two minutes against Dartmouth before breaking a bone in the same foot and missing the rest of the season.
As a result, Harvard didn't really have a true center last season, but the Crimson got along just fine without him, winning 27 games.
Isaiah Zierden, Creighton
Before dislocating his right kneecap and missing the final seven games of the season, Zierden was just a minor role player for the Bluejays.
He averaged 10.9 minutes per game and didn't exactly do a ton with those minutes.
But with four starters graduating this summer, Zierden should play a much bigger role in his sophomore season, provided that an underwater treadmill gets him healthy enough to play.
