This year's NBA draft doesn't have multiple franchise players like in previous years but it is very evenly spread out in terms of talent. A team can find a starter late in the 1st round and decent rotation players in the second round in this draft.
There is plenty of talent to be had just out of the pool of American prospects, and having a late first round pick won't preclude the San Antonio Spurs from getting a potential starter or all-star. The Spurs have already begun working out targeted prospects, some make you scratch your head (Matt Howard) and some are really intriguing like Justin Harper. What we know going into this process is the Spurs will do their homework on any guy in their draft range they have targeted and will make a wise selection. Any player they pick you should wisely presume will turn out to be a solid NBA player.
Based on need, presumed availability, and skill, I've compiled a list and brief profile on American college players that would be a good fit for San Antonio.
Chris Singleton - SF/PF, Florida State, 6'9'', 225 lbs.
A shutdown defender at the college level. He is very athletic and because of this athleticism, Singleton can defend both forward positions and is a very good rebounder. A blue collar type.
He made Kyle Singler's life hell in Florida State's victory over Duke in January, forcing him into a lot of tough shots, propelling Florida State to victory. He was perhaps the most complete defensive player in college basketball this year with his ability to defend the post and the wing. He can shoot the ball pretty well out to three point range but the rest of his offensive game is fairly limited as he doesn't really have a post game and can't create his own shot due to his lack of ball handling skills.
Singleton had surgery on a fractured foot in February and could slip in the draft depending on the outcome of medical tests. Right now he is projected as a mid to late first round pick with most projections having him land somewhere in the teens. If he fell to the Spurs, it could be another savvy draft steal for the San Antonio front office.
JaJuan Johnson - PF, Purdue, 6'10'', 221 lbs.
