I wouldn't say you are wrong but I would still expect Russel to take the MVP as I believe each voter cannot vote for a co-MVP so it would have to organically end up in a tie and I just do not see that happening especially with how absolutely insane Russel has been.
McNair and Manning were co-MVPs 2004 and Favre/Sanders shared the award in 97.
You’re right they can’t vote for co-winners but there can be a tie.
