"So if Montana is so good, why wasn't he in that proball your talking about?"
4-for-4 in SBs.
11 TDs in the SB.
0 INTs in the SB.
Most TD passes (5) in a SB (Steve Young broke it with 6, still a 49er record)
16 posteason wins...most all-time (now tied with Brady there)
128 passer rating in SBs (again, highest ever...no one's even CLOSE)
3x SB MVP (Tied most all-time with Terry Bradshaw for that honor...Brady has 2)
8x Pro Bowler (Including 1981, so a foul-up there, but Brady was in too, so, still...)
2x Regular Season MVP (again, tied with Brady, who has two...not the record, 3 is)
Named to NFL 75th-Annivarsay Team (Other QBs on list--Baugh, Otto Graham, Johnny U)
NFL Hall of Famer (Obviously...Brady will be too)
Played in an era of more defense than Brady
Played without as many QB-protecting rules as Brady has
The 1981 team's leading rusher had 543 YDs...HARDLY ground-breaking
Defeated John Elway in SB XXIV 55-10, again, biggest SB blowout, 45

QBs Montana beat in SBs--Kenny Anderson, Marino (HOF), Esiason, Elway (HOF)
QBs Brady beat in SBs--Kurt Warner (likely HOF), Jake Delhomme, McNabb
Montana never lost to the same QB in the playoffs twice
Brady just HAS lost to the same QB in the playoffs--IN THE SB--twice
Most games with a 120+ passer rating (tied with Favre, P. Manning, Warner, no Brady)
Most TDs in the redzone in the playoffs (32, ahead of Brady again...)
Most consecutive playoff games with 2+ TD passes (w/ Bradshaw and Brees...no Brady)
Most consecutive road wins in the playoffs (19, next closest--Eli, with 10)
Montana was a more mobile QB, rushing out of the pocket in a way Brady doesn't
Montana was a more accurate QB in the clutch (again--11 TDs, *0* INTs in 4 SB games)
For starters.
Not a lot for stats, but wins count a LOT...and as you can see...
No one was better, with the help and without, on the road or at home, than Montana.
