So you are saying that you didn't see the Chiefs defense carry them to this last Super Bowl? Truth be told, I wasn't even singling out Mahomes in the comment that I made about 65% YAC (although his is near the top of the league).
But this turns into a chicken or an egg thing. Do QBs elevate WRs or do WRs elevate QBs because I'm trying to think about who we consider "Top 5" and then I'm trying to think of them elevating receivers more than they were before they got there.
