Well, that's one hell of a leap to make in my opinion. There are plenty of scenarios:
1) They want to have depth at the most important position on the team and are fine with getting a 3rd round comp pick (assuming they don't go on a big spending spree in free agency)
If you don't believe that having the best back up QB in the league for one season is a reason to pass up a reasonable package of draft picks. How would you explain then the OTHER 16 seasons BB handled the back up QB position. It's never been an issue before. Why is it such a big one now.
2) They do not believe that Brissett is ready, and based on what we saw last year, why would they? How could they?
If Brissett hasn't developed into your cup of tea in his 2nd year, Ryan Fitzpatrick would be a more than admirable back up, who might actually get a lot better in this system.
3) They know there will be a market for him next year, and are fine with keeping him via tag/trade (probably unlikely, but still a reasonable option)
I actually wonder just how effective a franchise and trade scenario would actually work with a team who doesn't have Scott Piolli as a new GM and Mike Vrabel as an additional throw in. Also who knows how the QB market is going to look next season as well as next year's draft class will be.
This isn't a scenario that can work up to the draft. This is a scenario that only has a life of about a week after the start of the new year before it implodes. All the leverage lies with JG. By just threatening to sign it would force the Pats into a big problem.
4) Bill hasn't received as good of an offer as some here believe
I'm guessing we turned down a deal that includes the #12 among others, but I could be dead wrong, and I certainly wouldn't blame Bill for not moving on any deal that hasn't included that pick.....,at least.
If no deal ever happens I doubt we will know the truth about what was offered and what was refused, and of course it one does happen, we will know exactly what it is.
5) Bill does not want to trade him to a team within the conference, or to an NFC team he deems as a competitor
I think BB would RATHER trade him to a team that isn't a playoff contender (ie Houston) and rather to a non-conference team or a bad team like the Browns. But if BB got the right package of picks he'd trade him to any team outside of the division, and I'm not sure he wouldn't trade him within the division either.
6) Bill is waiting to see if Brady shows any decline before making what could be a very important decision
Doesn't matter about when and by how much Brady declines over the next few years. It isn't as much as Brady's clock is running out, as is when JG's clock runs out.
That's the point I'm trying to make. Everyone is talking about when Brady's clock will run out, but to me that's irrelevant. JG's clock with the Pats is what is running out so much faster. And the question is what is the best use of JG as an asset during the short time we still have him,
If you honestly believe its as a one year back up, then I'd respectfully have to disagree with you
