I google him from time to time, here is what I know.
Apparently Evans played in something called the Spring League. Its a league for guys that didn't make the NFL but are still trying. Him not getting a spot in the Alliance is NOT a good sign. I read somewhere that a little over 20 percent of players in the Spring League are on rosters in the Alliance, but not Evans.
Honestly I feel bad for the guy, some of his tweets were cryptic, but a little depressing in the fall. I don't question that he loves the game, and for all of us that thought he was a "me" guy or a cancer, or that he lacked humility. I think we all know now that a lot of guys can show signs of that. Willis came in with a huge chip and hadn't proved a thing. Josh Jackson is rumored to not be a saint, not a bad dude, but not perfect. Evans was a better QB than both of them IMO. I don't think JJ would have beat him out. I also don't think Evans left because he was "scared", if anything over confidence is what did him in.
Here is an article about Evans playing against Manziel's team in the Spring League last year.
