Former Celtic Grant Williams on how Rick Barnes helped him get into shape – brutally

Former Boston Celtics reserve forward Grant Williams made an appearance on ex-teammate Theo Pinson’s Tidal League “Run Your Race” podcast before he left Boston to sign with the Dallas Mavericks. He spoke about his time playing at the University of Tennessee under head coach Rick Barnes before being picked up by the Celtics in the 2019 NBA draft.

In one of the better tales told on the pod, Williams shared how received a FedEx box of snacks from his mom, including Little Debbie cakes and Orville Redenbacher popcorn, which led Barnes to tease him with popcorn while he ran on a treadmill at Tennessee’s fat camp.

Evidently, the tough love paid off given the Charlotte native is now the owner of a very lucrative second contract in the NBA.
