Gonna ask you again: when would you have moved Brady: before last season, during the season, or before this season?
The answer is, they couldn't have done any of those, and people that believe they could are lying to themselves.
What happens if they kept JimmyG, had to either franchise him, or convince him to see with the intention of dealing Brady (why would Jimmy do that? Why would Don Yee do that?), then failed to find anyone to take him they could cut Brady, the dead cap would've been detrimental.
Not to mention, what team is taking Brady at 40 years old when hes spent his entire career in the same offensive system? What team is on the cusp but needs a QB? That has Jets Brett Farve written all over it.
I get it sucks, because Bill had it perfectly laid out. Brady just played better than anyone ever expected him to this late in his career, and there was no other way around it.
