However, it was Mahomes who has won three Super Bowls with his team."The NFL is so weird these days... It's like, ok, you watch Justin Herbert and Patrick Mahomes play and it's pretty clear that Herbert is the better quarterback... Better arm, better mechanics, better reads, better presence, better accuracy... but Mahomes has 3 Super Bowls and Herbert doesn't even have a playoff win... And Lamar Jackson is the best player and hasn't been to a Super Bowl, it's all just very strange."The Chiefs take on the Philadelphia Eagles next at home on Sept. 14. The game will be broadcast on FOX at 4:25 p.m. ET.
