In games in which the amazing Lamar has played the Steelers, what is his teams record? Surely an intelligent semi-retired person as yourself can answer that question. Don't be afraid. The truth will set you free my friend.
Also, it is impossible to judge who is the "best player" in the league. It's an opinion. Lamar played 18 games this year. Mahomes played 20 games this year, and he has a Super Bowl trophy/ring as a reward. I am certain Mahomes could not care less who won the MVP.
Lamar is playing for second place. Mahomes is playing for rings.
