Former NFL head coach Herm Edwards said on SportsCenter today that he would have supported a gay teammate as a coach or player. When asked if the NFL is "ready" for an openly gay player, he said:
I think it is. I would have no problem with that as a coach or even as a football player. That wouldn't bother me. You're drafting a guy who already can play football. And if he's a good football player, if he can tackle, catch and run, score touchdowns, come on, get in the huddle and let's go.
Edwards was a player for (mostly) the Philadelphia Eagles in the '70s and '80s. He was also the head coach of the New York Jets and Kansas City Chiefs from 2001-'08.
For a guy who famously said, "You play to win the game," this sentiment shouldn't be too surprising. As long as an athlete can help him win, any coach should say the same thing.
