1. Mike Muscala
Mike Muscala was acquired by the Boston Celtics from the Oklahoma City Thunder at the NBA Trade Deadline in an attempt to solidify the team's frontcourt depth. Though, he's only appeared in just a handful of games for the Celtics. He has a team option for next season but there's no guarantee that the Celtics will accept it. If it is declined and he does enter free agency, he could emerge as a veteran option for a team like the San Antonio Spurs.
Muscala is a stretch-5 that could work as the third or fourth big off the bench for the Spurs next season. He'd be a relatively cost-effective signing and would offer insurance behind Victor Wembanyama and a veteran presence in the locker room.
