It doesn't matter. The argument has ALWAYS been that mobile QBs will NEVER win a SB. Wilson took practically every snap for the Seahawks this season and WON the SB as a mobile QB.
The argument against Cam is that he cannot win a SB because he is mobile, which if you look back at the history of mobile QBs in the NFL, they have been fairly successful given how few there are.

You can be the best prototypical qb in the league you are not guarantee to win the super bowl
Without the right pieces you can't win the big ones.
