Was he asked the question or did he bring the subject up on his own?
I am guessing that the was asked the question. Presuming that is the case, then that is pretty much the best answer he could give, would you not agree?
If he said anything else it would just lead to speculation that he plans on leaving.
Besides, it's really a moot point. Worse case scenario is that the Patriots place the franchise tag on him next season while they work out a contract. Remember all the speculation that Vince Wilfork was unhappy and was going to leave two years ago, the 'disconnect' between Tom Brady and Robert Kraft that some yahoo sportswriter wrote about and was accepted by many to be fact, and all the angst over Logan Mankins' contract situation prior to this season?
