if you are implying a trend (QBs over 35 not winning a SB), then any attribute that separates him from the sample is extremely relevant n determining how strong the trend is on the individual. You wouldn't compare him to QBs who only started one season in their NFL career and say that would you? You chose a flawed subset.
It would be like saying how many college Quarterbacks go on to the NFL prowbowl and then using that number to say that Andrew Luck's chances are small, ignoring the fact that clearly he's not got a lot in common with the vast majority of QBs in college already. Do you think Andrew Luck only has a 1/1000 chance of making the NFL probowl? His past accomplishments are irrelevant right?
New question:
How many multiple SB-winning QBs have won a SB over the age of 35? Certainly changes his chances doesn't it? How about - how many multiple-SB-winning QBs that have played past the age of 35 have won a Superbowl?
I wouldn't bother, this guy is either trying to get everyone riled up, or he is just very dumb. Numerous examples have already been pointed out including QBs that have won the SB past age 35 and QBs that were very close recently and easily could have won the SB (Favre, Warner, Gannon.)
I think the major point here is that most QBs are not even in the league past age 35, which is why you are isolating about 5% of active quarterbacks each year and stacking the odds heavily against them. In recent memory, these are the only QBs I remember playing at that age:
Steve McNair- Led the Ravens to a top seed in the playoffs in 06
Brett Favre- As already stated, was twice within a field goal of going to the SB with Packers and Vikings
Rich Gannon- Made it to the SB in '02
Kurt Warner- Had the lead in SB 43 and should have won in 08
John Elway- Won two SBs
Matt Hasselbeck- Played well last year; the problem was elsewhere on the team
Vinny Testavarde- Put together a great season in 98 with the Jets
In fact, the only QBs I can remember that were given a chance to start after age 35 and were terrible were QBs that were already terrible like Kerry Collins last year or John Kitna who couldn't have won during his prime. I'm sure I'm missing a few, but again, if a QB can still play that late into his career, it actually seems like an advantage based on that list.
Aikman, Montana, and Bradshaw did not play past 35.
Marino played until he was 37. Same with Young. Kelly was 36. So basically that accounts for about 5 total seasons where HoF QBs did not win a SB. Wow, what a curse.
You definitely could argue that QBs get progressively better as they get older until injuries eventually end their careers. I'm personally not a believer in running ability and arm strength as big indicators of a successful QB, as so much of it is mental.
