In the age of the one and done, you need quality 4 year role players to go along with the early departed.
I agree that length is certainly a good thing to have at the top of the zone. But I think Girard makes up a little for his height, with what would be his ability to see what's coming and anticipate. He's not one of those kids that has to think about what he is doing or going to do. Not just that, but he is not as slow footed as many think. Watch some of his football highlights and you can see he is not slow, or slow footed. Nor is he a slacker, his hustling would also help make up a little bit for his height. Kid is a gamer and wants it. His arms/hands will be up all game and not down like many in the zone sometimes do. He'll be on the floor scrapping for loose balls. Could he guard a Colin Sexton or Trae Young 1on1 all game. No. Good thing he wouldnt have to in a zone. Ty Jerome and others are not blowing by him at the top of the zone. Not with help the wings provide. Now if he were to have to push out and guard a guy with deep range, that guy might be able to drive on him, but otherwise I don't see Girard being to much of a liability up top.
Doesn't hurt that kid might be one of the best, pure 3 point shooters in his class and can hit from anywhere once past halfcourt.
Hard to imagine how much better of a shooter/player this kid could be by the time he would be a senior five years from now. 6 if he were to redshirt.
Extend the kid an offer at the very least.
