This is part of the problem. Most valuable.
Barkley isn't winning 8 games in a full season with this team.
Meanwhile GB has the best oline, one of the best rb for yards per att and best TD per reception wrs in the league.
Mahomes has the best TE and fastest WR in the league and one of, if not the best, coaches in the league.
Allen has done more with less which is why his value should be higher but it's not because they mostly just look at the box score and stat sheet.
