I think ESPN's reporting of the "end of a dynasty" is both jumping the gun and way overstating the issue. However, that doesn't make the specifics any less real or less interesting.
As far as the JG trade, it's interesting what is being reported as far as BB's stance on not wanting to do it and being overridden. But that aside, it's easy to "Monday morning quarterback" it now that JG is 5-0 with the '9ers and practically looking like the second coming. Given his contract status, etc., they got what they could for him, and this shouldn't be seen as a "bad" trade for the Pats. I mean, fair play for those who want to argue that they should have paid him whatever he wanted and either traded Brady next year or the year after. But that option aside, if they were going to trade him, the fact that he is now exceeding expectations in SF doesn't mean it was a bad trade. Under the circumstances, it wasn't.
It would be really interesting if he leveraged his performance in SF to get the the Pats to offer him enough money to come back, and he actually did so. 49ers fans would be PISSED, and rightly so, IMO. But, man, talk about an intriguing story. That would be one for the ages if it happened and a continuing dynasty (ala Steve Young era 49ers) was built around him.
