I don't think there's any disagreement that we'll need a quality point guard in the 2013 class. Pe'Shon Howard will be a senior in '13 as will Terrell Stoglin (assuming he stays in school), and Seth Allen is a combo guard who is working to improve his point guard skills, but is a natural 2 guard.
The Harrison twins are our #1 target for 2013, and would solve the problem of losing Howard and Stoglin. In addition to a point guard, we have our sights set on one of several potential centers in '13, with Kennedy Meeks, Dominic Woodson and now DeMatha's BeeJay Anya seems like he is open to considering the Terps.
There has also been a good deal of discussion about adding a power forward in 2012. Charles Mitchell, JaKarr Sampson, William Howard, Chris Obekpa and Phillip Nolan (3/4-star prospects) are all considered possibilities to fill that role. Adding Baltimore-area shooting guard Sam Cassell, Jr. (unranked on Rivals, 2-star on ESPN), in 2012 also seems to be a real possibility.
Here's the problem: If we add Cassell and a power forward in 2012, that leaves two available scholarships for the 2013 class. If the twins choose UMD, getting Meeks, Anya or Woodson in '13 would require an existing scholarship player to leave, or some kind of scholarship "adjustment" to be made.
Is adding Cassell with his Baltimore connections, or adding a power forward with Pankey and Len in the fold worth risking not having schollys available to get twins, or losing Meeks, Anya or Woodson for lack of scholarships. Hence, When is a bird in the hand not worth two in the bush? Is taking Cassell or a 3/4-star power forward worth losing a 2013 target? Do we need to start being selective about who we add to the 2012 class?
