Guys, he has demonstrated he actually is an average jumper. Although he's clumsy and awkward, he's certainly strong enough for D-1 and, eventually, professional bball. Although he tends to over-favor his left, and is a bit mechanical / deliberate, he actually has some very decent block moves that can create space for decent, unobstructed shots.
For these reasons, I really don't think a red-shirt would have helped Woody that much because he did / does have skills and physical readiness to play. Believe it or not, he is a legit 4* (maybe 3-1/2) regarding skills, athleticism and all-around game.
His problem is he's <1* on the 5-position IQ and mental approach to the game. He simply fails to understand that a post needs to be the most physical, mentally intimidating player on the floor. He doesn't "own" the lane, let alone, send that message to the opponent. He doesn't attack the basket with the intent to rip down the rim. He doesn't create contact with the intent to go through the defender to the basket. Sure, he lowers his shoulder to try to go around (usually into) a defender but that's where his focus is -- the defender -- rather than on the basket with the intent to score.
I'm not sure if it's confidence or a weak mental approach to the game or he's too laid back to muster up the intensity and aggressiveness that a 5 needs to have. I do know the result is that he is simply soft -- a classic "marshmallow". Unfortunately, no red-shirt, no coaching, really no external influence is going to change that. It's too bad for the Hawks and, for him, personally / professionally, because he it limits what are actually capable skills and athleticism that could contribute to W's and make him a lot of $$.
