- The Celtics were among the teams that attended John Wall‘s private workout Sunday in Las Vegas, tweets Kelly Iko of The Athletic. However, Brian Robb of MassLive doesn’t see Wall as a good fit in light of the team’s recent moves. Boston signed free agent point guard Dalano Banton this summer and already has Derrick White, Malcolm Brogdon and Payton Pritchard on the roster. The Celtics are already facing a significant tax bill, Robb adds, and any free agent addition would bring millions more in tax penalties. Iko identifies the Trail Blazers as another team that sent representatives to watch Wall.
