These are good points. I think Goodwin's percentages were better at the beginning of the year though. Later on, he tried to force things, and part of this was because Noel got injured, Poythress was still passive, and Harrow was inconsistent as a PG. Goodwin was asked to do more offensively and as a creator than he was really ready to do as an 18 year-old freshman. It's worth seeing where he is mentally. The physical talent is unmistakable with size, wing-span, quickness, handle, aggression, endless motor, instinct, etc. If he has the right attitude and work ethic the ceiling is just really high.
You look at other prospects in this draft, and most of them have a significant flaw. Burke is undersized. Noel has little offensive game, is a bit of a tweener PF/C, and got injured. Shabazz is a one-way player. Bennett is too heavy to drag his butt all over the court like an SF all night, but he's too small to be a go-to PF. Carter-Williams can't shoot and doesn't have much change of pace. Porter is well-rounded, but doesn't stand out with any go-to skill. So maybe he ends up like a more skilled Jeff Green. The bigs are good, but not dominant. Oladipo doesn't create. The one guy you can't complain much about is McLemore, but he needs to be more assertive. Archie just stands out to me as someone who could be a game-changer. He's a prototypical 2-guard for today's game.
Don't assume that Kentucky was a stellar program this past year. The whole team was a reset and they underachieved. It's not all on Archie.
