i might give dzanan musa a shot as a buy low guy - averaged 20 and 5 in the ACB league on 50% FGs and 38% 3pt - 63.4% TS. his 20 ppg led the league in scoring by a wide margin (2nd place was at 17 ppg). he just turned 23.
The Mavs just held a veteran free agent mini camp with 30 some players with a lot of the same guys the Jazz had in. Tyreke Evans was the "star" of the group. If he's clean and sober there might be your guy.
