1. Patrick Mahomes, Kansas City Chiefs
Patrick Mahomes is the best quarterback in the league so it is only fitting that he is no. 1 on this list. By the time the 2021 season is over, there are going to be very few quarterbacks that are better than Justin Herbert and he is going to be one of them.
Unless he takes a huge nosedive in his career he is going to be the best quarterback in football for at least the next decade, period. Justin Herbert can definitely get on that level with consistent play and team success for the LA Chargers, but the casual NFL fan will still lean towards Mahomes.
To be fair to Herbert, though, he simply did not have the same luxuries in his first season with the LA Chargers that Mahomes has had in Kansas City. Herbert did have Keenan Allen but he did not have a Hall of Fame all-time tight end in Travis Kelce, a great (let alone competent) offensive line, nor an offensive genius as a head coach.
Give Justin Herbert those things and he does just as good as Mahomes. That is a hill I am willing to die on.
It is going to be extremely fun to watch Justin Herbert and the LA Chargers battle with Patrick Mahomes and the Kansas City Chiefs for the next decade.
