The main reason why people hate Mahomes is because he’s boring. This isn’t a criticism of his personality because it’s what every head coach wants. They dream of players who live and breathe football. That describes Mahomes perfectly because he’s all about Kansas City and his family (via NBC).
Even his bachelor party was a relatively tame affair in Las Vegas. Yes, he had a few drinks and enjoyed some time with his boys but it wasn’t a dramatic event. Meanwhile, his house is relatively modest compared to some celebrity mansions. His main indulgence is a room he dedicates to his sneaker collection.
