Are you new to this football watching thing? Do you think Montana is GOAT because he put up gaudy stats and not based on the 4 super bowls?
He's the GOAT because he held up his end of the bargain in the regular season and playoffs better than anyone. They won superbowls becasue they had the best overall team and legendary coaching. Joe was a big part of that, but you'd be naive to think if Joe was on a modereatly talented team he'd still win four titles.
I'm banking on the 49ers to be the D that gets that turnover. Matt Ryan has put up great games like this before and still managed to throw interceptions. If the 9ers can get some pressure on him I can see a mistake coming.
