I grew up in Huntsville so the Condredge family story(s) are ones I'm familiar with: both father and son. (Did you know his dad was the first black employee at NASA working at Marshall SFC?)
Did I watch him? In the fall of '72, his first season playing for the Vols, I was getting my ass spanked daily: in Kindergarten. So, no. Not really. But yes, I have in old films.
There's a few versions of that story tossed about. I've also heard Bryant wasn't a fan of him playing baseball and football.
It's about like the Cunningham stories. There's a lot of them out there. You're missing my thought here though. Even today we're seeing coaches look at QB's and see them as DB's. That's nothing new to football.
