Hard to say what Coffey communicated to Pitino but if there is a chance he comes back no recruit would accept the scholarship contingent on Coffey not getting drafted and have to wait until after the NBA draft day to find out the results, they will go elsewhere by then, either Coffey comes back or that scholarship goes to a walk on for a year.
I don't see why a player, say, for example, Crowley, would base his decision on Coffey being here or not.
