The Denver Broncos have featured one of the least impressive offenses in the NFL, and the team already fired offensive coordinator Mike McCoy because of it. Could receiver Demaryius Thomas be next up on the chopping block? According to one report, the Broncos tried to trade him and might move on after the season.

Benjamin Allbright reports Denver believes Thomas lost strength when he switched to a vegan diet and hasn’t been the same player since.

Thomas has caught 53 passes for 633 yards and three touchdowns this year. Those aren’t awful numbers, per se, but considering he caught 402 passes for 5,787 yards and 41 touchdowns between 2012-15 with Peyton Manning as his quarterback they’re quite low by comparison.
