Point 1: Mahomes played in 73 games, Dak only 56 and Dak still has him beat in 400 yard games.
Point 2: Mahomes has a god-like receiving unit. Dak has a very good receiving unit but it doesn't compare to Mahomes'. Kelce + Hill > by far anyone we got. Cowboys are receivers by committee. Chiefs have a receiving unit that have been proven unstoppable by 31 teams.
Point 3: Wins are a team accomplishment, so Mahomes didn't win those games on his own.
Again, Mahomes > Dak overall because of his Super Bowl and his postseason accomplishments, but lots of his games are simply because Chiefs are good enough to jump ahead and beat teams without Mahomes needing to do much. Cowboys has a bad defense most of the times, 0 dominant D-linemen, a used up starting running back, and an O-Line that blew the SF playoff game badly. Mahomes O-Line was horrendous in the Super Bowl, but at least they chose the last game of the year to be bad in.
Thoughts?
The problem with your analysis is your basing it on stats.
Dak is clearly the stats champ, as that is why he is called stats prescott !
Dak is the best stats qb in the nfl.
problem is the bulk of those stats come in garbage periods of comebacks, most of which dallas loses anyway.
Mahomes isnt perfect, but the reason people herald him, are some of the plays he makes.
He plays like young Romo, only better as he can run better and better at throwing while rolling out.
He just makes some great plays every game, and is also pretty smart and makes mostly good decisions.
If you put dak on the chiefs, ( why dont you talk them into a even trade, mahomes for Dak !!) he would be better and win more.
Because he would have better coaches, culture, normal FO and coaching set up, and like you say better TE, but tyrek is gone.
But if you brought mahomes here, he would do better than dak even in this mess, lol , but I dont know if he could get them to a SB or win one.
To get to a SB in dallas , you would have to overcome the whole mess that permeates cowboys, which all comes from the jones boys.
That is hard to do, so I dont blame dak for his playoff losses, that is on the jones mostly, as they hire and set up the coaches mess.
