At this point, the only people hoping for Franks to go pro are folks who want the basketball team to stink so maybe Kent gets axed. One Cougar blogger in particular comes to mind.
Franks has a lot he can work on to make him a better pro. If he gets feedback from NBA scouts, they can tell him where to step up his game. Focusing on becoming a dominant rebounder and an above average defender seem like a good place to start. As would working on his low post game or attacking off the dribble from the outside. Both get him to the charity stripe more often. Scouts will tell him what they prioritize, but he could be a lot better by improving 1-2 of these areas in his game.
Franks has the opportunity the become one of the conferences most dominant players, which would set him up to be a great pro. He's already made huge strides but he's not ready yet, that much is obvious, and the NBA's best developmental league is the NCAA.
