re: So was Keith McCants an NFL bust?

This.

I actually chatted with Keith a lot on social media. He wasn't bitter but said the professional football machine chewed him up and spit him out. He did get addicted to pain killers and battled that a long time.

He did say his move to DE was a mistake but in the NFL you play where they tell you to play. He seemed like a really genuine down to earth dude.
