Brantley is our version of Paul Millsap. He can spot up from 3, move the ball, make a play off the dribble and finish inside. He wasn't ready as a rookie to contribute, and the Jazz didn't have a glaring need for him last season (like they had a glaring need for Morgan to defend big 4s and 5s). I think Brantley is a rotation player as soon as he's ready. If not, the Jazz can trade him and get something back.
FWIW, if the Jazz draft Woodard, I don't think he's going to play meaningful minutes as a rookie. Shooting, passing and decision-making are all question marks with him, imo.
