I don't have a crystal ball to predict what me or you can get for him right now, but the fact is that the "general public" is onto this guy now. The hype has exceeded what this guy is capable of this year in my opinion. Let's remember some things- Pete Carroll is fickle and will do whatever to win- do if Russell has a bad game, Flynn could be the starter week 2.
Also this remains a run first offense with little to no outside playmakers . And on top of this russel is small and has to be more susceptible to injury than a larger qb .
And since the public is onto this guy now I just think you move him for nice assets. . I think the guy who wants Ryan Williams can get more but I can't speculate on what. I just feel like selling guys at hype points like this is how to win championships .
