OK...recognizing that I am the new guy with zero credibility here...
I am at least as big a RW fan as PC, and have been since about 1/2 way through his first game for my alma mater. One of the many things that impress me about RW is how he does what he does and avoids the big hits. That said, in my just over 50 years as a player, coach (kid ball) and fan, I have seen that anyone can get hurt...and the more you put yourself out there, the more chance of that happening.
My point is that, while RW is clearly the guy, I believe that (especially after years in a GB system that has a pretty good history with QBs) Flynn is one of the top backups in the league and is better than many starters out there. It really wouldn't take a lightning strike...especially with the ever increasingly more stringent concussion protocols mandated by the NFL...for the Hawks to need someone who could step in for a half, or a game, or a few games and keep the team in competition while awaiting Russ' return. How many would like to see the Hawks forced to do what Washington did and either risk the future of their franchise QB by playing him hurt or make do with a some guy who has never played a game in the NFL? Who would one like to see backing up Russ this next year rather than Flynn?
To me, for a difference of about $2M-$3M to a team with a ton of cap space, Flynn seems a good enough insurance policy for at least one more year. I really cannot imaging him getting cut for no compensation.
Now, if there were a trade offer that would produce a big, fast WR with fantastic hands...that might be a different story
