Right, because the person, aka their leadership style (or lack thereof) and how they don't listen to coaching, is the reason why Wentz got traded. He didn't get traded because he played bad. He was better than Philip Rivers ever was in Indy, and was easily the best QB they've had since Luck.
His TD% was 11th in the league. He doesn't turn the ball over (3rd lowest INT % in the league). If you're into things like Passer rating and QBR, he was 13th and 10th in the league.
Those are not stats of a bad NFL QB. They're stats of an average NFL QB. Average NFL QBs don't really get traded all that often either, and certainly not for three consecutive years. Average NFL QBs who are bad leaders and don't respond well to coaching get traded.
The latter is the most important aspect of this. If Carson Wentz was a great teammate, he'd either still be an Eagle, or he'd definitely still be a Colt. His play isn't bad enough to warrant the treatment he's gotten.
I would think that would also be further verifiable by the fact that Washington gave up multiple mid round draft picks AND are willing to pay the guy $22M to play for them, even though they likely know his leadership challenges.
If you want another comparison of how leadership matters... Carson Wentz, from a talent perspective, isn't much different than Kirk Cousins. Both have limitations as passers, but both generally take care of the football well, have won games with multiple teams, etc. One makes a boatload of cash for a team and stays put for many years, the other gets traded twice in three years. The difference between them isn't talent...
