I mean if you go back to 1988 you've had 30 Superbowl winners and only 8 of them weren't led by future HOF QBs.
Nick Foles, Joe Flacco - both played lights out football through the playoffs
Brad Johnson, Trent Dilfer - both had absolute generational defenses
Eli Manning - nothing needs to be said - just some beautifully freaky stuff going on
Jeff Hostelter - honestly don't know anything about em
Mark Rypien - same story, don't know anything
Look - maybe I'm being a bit exaggerated in my statement, but 8/30 or about 26% are Non-HOF QBs. A couple of em had generational defenses, so, yea...phenomenom sounds right.
Also, if that's why you can't take an argument criticizing Tannehill seriously? Then you're just digging your head into the sand unnecessarily IMO.
"you think you need an elite QB to win a Superbowl? well, then your criticism of Tannehill is invalid."
nah man
