There's nothing wrong with giving an opinion that a player isn't going to pan out as a Division I basketball player, but I think the original comment unintentionally came off as being bitter that the player chose another school. Now it is apparent that is not what was meant.
I don't know anything about Mikesell, but I will say that the conference St. Henry is in is probably the best small-school conference in all of Ohio. This is especially true for football but other sports as well.
