The article I posted ranked each individual single game performance of all 49 MVPs.
Your article includes cumulative review of a players (MVP or not) total Super Bowl performances though all the SBs they played in.
These are not necessarily inconsistent.
Just looking at the #1s from each. Montana in XXIV is a good choice for best single game performance by an MVP.
Brady’s general excellence across 6 SBs is a good choice for best performance by a player in Super Bowls, cumulatively.
Yeah, this is all and only about... Cam's athletic ability--
