I say 2015 was five years and several surgeries ago. The guy had two offers.
Tom Brady was a late round draft pick.
Assuming teams are genius is not really a good way to handle this topic.
Cam has significant risks.
He had a series of injuries and off the field mental health/happiness question marks.
But pretending Carolina had good offenses or comp[arable overall talent/coaching to Carolina would be disingenuous.
And no one is going to accuse Ron Rivera of being a good offensive mind.
In his last starting work in 2018 he wasn't that bad. 24 TD passes, 3400 yards passing and 94QB Rating. He added 100 rushes for almost 500 yards on the ground.
The team was trash though and that's what people recall.
Brady has issues as well but for very different reasons.
He's already the oldest QB to win a SB by a few years.
The prior oldest was Peyton at 39 years old.
Brady last year had an 88 QB Rating and passed for his lowest yardage total in a full season since 2010. He had the same 24 passing TDs as Cam did in 2018.
I think from a pure football standpoint people are ignoring going from a quick-read veteran laden team with every coaching aspect covered ad-nauseum to a deep ball big-play system where he is bringing all the offensive knowledge,
