I believe he might be slightly mistaken:
Joe Montana & Steve Young took every snap under center.
EVERY SINGLE ONE!
So when you're out there having to debate the greatness of these guys, just know how good they were that they didn't have that little crutch that all other QBs we've seen play since the '80s have. Peyton Manning for instance it seemed like he rarely ever goes under center.
When Montana lobbed that beautiful sideline bomb to Rice to beat the Giants in the '88 season, facing a 3rd and 10 from his own 22 with under a minute to play.....no shotgun.
Some non Niner fan said the most interesting thing about Montana: "I've never seen a QB cover so much yardage in his drops than Montana". Kinda true now that I think of it.
The best compliment I think to this trivia is I told this to a random football fan and he was like "NO WAY, THAT CAN'T BE TRUE! I NEED PROOF".

* - Now it's possible they might have, but I really doubt it (and if so, I wanna see it!). I first learned about this reading it in an article written by Young where he said he preferred not taking his eyes off to catch a snap so he can always be reading the defense (and I believe he included Montana in this).
After reading that I thought about it and was like "oh s****, that's right, I've never seen them in the gun".
