If Whaley or Hill aren't returning, than Josh Jefferson makes a TON of sense. Otherwise, apart from his relationship with DJ, I'm not sure what the role would be for another 4 who shoots under 30% from 3 and generates most of his offense from inside 12 feet.
This team desperately needs a wing shooter, preferably a 3 and D with some length, and a secondary ball handler, and then a shooter of any size well before we have any need for frontcourt depth. Maybe Hicks can groom his game to fill one of the two latter needs, but that still means we need at least 2 quality back court pieces.
