The whole "Wade needs Radford in order to be good" is just looking for an explanation on Wade's poor play. Wade had plenty of bad games last year when Radford was in.
We saw bad games from Wade last year, but he countered them with 2-3x the good games so it was tolerable. The hope was he'd take that next step this year, but he's reverted.
My completely random theory from watching -- a whole lot of Wade's game last year was driving to the hoop, initiating contact, and getting to the foul line. Not exactly Harden-esque, but manipulating the game to get to the stripe was definitely a big part of his game and why he seemed so mature for his age.
In a few early games this year (I believe 1H Iowa State? Not sure), he was very obviously not getting those calls anymore - to the extent that I believe even one of the refs said something to him about "knowing who he is" or the like.
I think the tape got out on Wade and the opposing coaches early made sure the refs keyed in on that he was initiating the contact on the drives, not the other way around. Refs swallowed their whistles on it in some early games, and since then it seems like Wade has been reluctant to drive to the hoop at all. So what we've seen is rather than 10 deep shots not falling -- ok I'll drive to the hoop and get to the foul line... we're now seeing 10 deep shots not falling -- ok I'll chunk up another 10.
