I'll be stunned if he isn't much, much better than Reddish. I've watched some whole game footage. Much tighter handle and more aggressive on drives. I don't have a super strong opinion on his jumper. But most scouting reports say it's good.
Also, Biancardi must be using "switchable" very loosely to describe his defense. Then again, I guess he could mean that he guards every position equally badly. Struck me as a problem of awareness more than anything.
