We must be watching different games. mahomes took over and the chiefs were nowhere near a SB. They were nothing more than a solid team that could be anywhere from 8-8 to 11-5 and MAYBE win 1 playoff game and then they were gonna be done. The Chiefs won 12 games 1 time in the previous 11 seasons prior to Mahomes...... they have won 12-14-12 in the three since he took over.
Starting in 2015 and moving to 2020 here are the chiefs points per season: 25.3, 23.8, 25.6, 34.8, 29.9, 28.5.
Take a guess the season Mahomes took over.
Starting in 2015 and going to 2020 this is the Chiefs Points allowed per game: 17.4, 19.4, 21.2, 26.2, 20.2, 22.8
So defense actually has allowed more points since Mahomes took over. The year he took over, the defense was statistically WAY worse as far as points per game.... and yet when they had the number 1 defense as far as points allowed in 2015, they made it through 1 wildcard game and got the boot. No elite QB and statistically you arent gonna do well.
