Most accurate? Nope. Most athletic? Nope. Biggest arm, most mobile,best pocket passer, best touch, best anticipation. Id say no to all of those.
Does he have the coolest looking off script out of the pocket plays, yes. That isn't the most talented. That's just the flashiest.
I don't know baseball that well. But i would assume it's like saying the guy with the most homeruns isn't necessarily the best hitter.
As for leader how tf do you even quantify that? I mean i don't disagree that he is a great leader. But he isn't the only one who leads in the way that he does
