“They are probably two of the most physical guys in the league,” Thornwell said. “It ain’t fun going against them, though, when you get hit by one of those screens.” Opponents, teammates, even team staff — no one is ever truly safe from the wrath of these picks. Prior to Williamson’s debut last season, the Pelicans had him playing 3-on-3 and 4-on-4 games against staffers, coaches and players out of the rotation in order to ramp his conditioning up to get ready to play in a real game. Multiple sources told ESPN that after one such session, a Pelicans’ staffer was sent to a local hospital to get checked out for a possible concussion because he ran directly into a Williamson screen, eating a faceful of arm in the process. (The staffer was OK).
