Brady doesn’t look like he’s ready to take up the rocking chair just yet. ?
And more manufactured hype this year, as well.
He certainly has nothing to prove at this point. If he's still enjoying it and can produce, go for it.
The only downside of keeping a marquee quarterback in the spotlight when he's into his 40s is if it means backup quarterbacks get fed up and leave, only to produce terrific numbers somewhere else. Or by the same token, never get meaningful reps behind the marquee guy, and end up with unspectacular careers doing short-yardage or holding place kicks, without a chance to develop anything more meaningful.
