I am confident that a deal will get done, although for my (our) own comfort, I (we) wish it were done already. One thing to keep in mind, however, is that the agent said very clearly that his preference is to get his clients to FA in order to let the bidding process kick in. This backfires now and then, but rarely, if ever, for a franchise QB. I strongly believe this is the strategy they'll follow here.
Russell is going to get paid, so the only answer really is "when" and by "whom". Going off of the agent's remarks, "when" is likely not until after Year 4 at the very earliest (a bit of a gamble) and "by whom" is the top bidder. Recognizing that the franchise tag is not friendly to the Seahawks' cap, it seems pretty clear that the Wilson camp feels it has more leverage than the team. Wilson is quite content to gamble on his health and ability while making Top 5 average for a few years if it means getting to some number, and they clearly have a target.
The only way to guarantee some certainty with the team is to meet that number, and I suspect it is HUGE...not Aaron Roger's plus $1. Time will tell.
