"[He] had what looked like softballs in his shoulder that he had repaired after the season after the fact," Campbell said in 2021, via USA Today.
"It just looked like a bunch of calcium deposits that had been in there. You wonder why when you watch the film last year why he’s not using his arm. It’s because he had issues."
