Confused why my running back is up for the heisman

Started a dynasty with Texas on heisman. 5 games in my rb Wisner is 2nd in the Heisman voting but he is 63rd in the nation in rushing with 428 yards 5 TD when the rushing leader has 762 with 9 tds and the rushing td leader has 16. He also has 141 receiving yards and 2 tds but I don't understand how he is up for the heisman. Ryan Wingo my wr is third in the voting but he is 4th in receiving yards(605) with a 20.9 average and 6tds.

The other players up for the Heisman are Gunner Stockton(1st) with 1864 17 tds 1 Int, Wisner is second, Wingo third. Diego pavia is 4th with 1264 9 TDs 0 Int 553 Rush yards and 7 tds. Jerimiah SMtih is 5th with 620 yards and 8 tds. I just don't get why Wisner is up for the Heisman when he hasnt been the player of the game or week at all and he really only had one great game at Ohio St. and had around 70 to 80 yards in the other games. Tbh I'm just curious how the game decides who is up for the award; Arch has 1654 yards and 16 tds but he fell out after i just ran the ball against a scrub team with my backup rb. Other than that i have the 5th worst pass defense in the county and the 4th best run defense lol
