So far this season we've all had discussions regarding next year's team and whether it will feature Grant and/or Ennis. And, no matter how much we wish it, chances are probable that at least one of them - most likely Grant - will bolt after this season.
Ennis, I think, we're all on the fence about. Much of this is because his emotions are never known. We can never tell what he's thinking.
Now, I believe the point was made recently that Grant would benefit from a 3rd year, and I completely agree. He can develop a more polished all-around game and go from low-first round to lottery pick guaranteed. Right now I think he's already a first-rounder because of the way NBA teams draft players nowadays.
Meanwhile, this recently was posted (http://insider.espn.go.com/blog/jeff-goodman/post?id=2915) and leads me to believe that Ennis will only stay if he feels there is some "unfinished business" or if he feels he can improve his stock, which is apparently moving further and further up the charts.
It's the latest rankings of freshmen on ESPN.com and Ennis tops the list. Couple that with his team's performance BECAUSE of him and, well, if he leaves we really can't fault him.
