I said it earlier and I'll say it again. I think playing time matters. It's why the MVP race is perceived as a two-man race between Curry and Harden who played 80 games or more (so did Chris Paul) while Anthony Davis, Lebron James, and Russell Westbook aren't treated as legitimate contenders in anything I've read.
It's close enough that missing eight games with a bruised back could have cost Thomas the award, just in case you were looking for another reason to hate D-Wade.
