Whatever else happens in his career, remember this version of Patrick Mahomes.
He is 27. He has won two Super Bowls and played in three. He is the best quarterback in the NFL. He is the most valuable player in the NFL, if the word "valuable" is to continue to hold meaning.
Will he prove to be the best quarterback of all time?
That will require health, luck, coaching, general managing, savvy drafting and many other factors out of his control.
Even if all goes right in his world for the next 10 or 15 years, he might never match Tom Brady's statistical or championship totals.
That's why we should always remember what Mahomes did on Sunday night in Arizona, when he led the Kansas City Chiefs to a come-from-behind, one-legged 38-35 victory over Philadelphia in Super Bowl LVII.
Playing on a sprained ankle that bothered him enough late in the first half that backup quarterback Chad Henne began preparing to go in the game, Mahomes didn't miss a snap, overcame an underwhelming first half and a 24-14 deficit, and led Kansas City to a victory over a team with a deeper roster.
In the second half, Mahomes completed 13 of 14 passes for 102 yards and two touchdowns, and the Chiefs scored on each of their second-half drives.
