It goes without saying that most will vote 'yes' in light of his 6 TD performance yesterday.

I guess so, but it just seems that when people talk about current QBs that will be in the HOF they say:
Favre
Manning
Brady
Maybe Warner, maybe McNabb. I think Brees' name is rarely floated, I guess because he's still in the prime of his career. But I think he now has a great shot to make it one day.
With a great year this season (certainly off to a fine start), he'll have 4 great seasons ('04, '06, '08, '09) to his name. That puts him close to a HOF lock.
Well, there are reasons why those players are mentioned and Brees isn't:
Favre has all the records, 3 MVPs, a Super Bowl championship, and another Super Bowl appearance.
Warner has regular season statistics comparable to Brees, but blows Brees away in the postseason, including 3 Super Bowl appearances and 1 championship... plus 2 MVPs.
Manning at age 32 is already top 8 in numerous passing statistics and stands a good chance of surpassing Favre there... plus he has a Super Bowl championship and 3 MVPs.
Brady has one of the best single seasons ever and 3 Super Bowl championships.I think it is terribly premature to ask about Brees at this point. He's got one 1st team All Pro selection, 0 MVPs, and 0 Super Bowl appearances. His highest rank in compiled statistics is #37 in completions. But he's only 29 years old. If he keeps it up long enough, especially if he wins a Super Bowl and/or an MVP or two, he'll have a good chance.
Check back in 2-3 years.
