Bottom line is the typical black QB will not succeed in the NFL as often as a white NFL QB. Call it stereotyping, call it racism (though I don't see how it is)... they're stereotypes for a reason, because for the majority they are TRUE.
Do you have any evidence that typical black QBs will not suceed in the NFL as often as white QBs? What are the sizes of the populations, and the opportunities they were granted? What, you don't have any data, just bigotry? That's what I thought.

Ladies and Gentlemen- the Shark Pool...
This is why it's impossible to have an intelligent conversation in this thread. Someone states an opinion about a black QB and everyone screams bigotry. So if I didn't vote for Obama I'm racist too?
If you continued to read my statement instead of stopping at that last sentence you quoted, you'd see that I backed it up with opinion. You want stats? You can't handle the stats. How many black QBs have won a superbowl? One, Doug Williams. How many black QBs have been converted to WR in the NFL? Compare that to QBs, you'll find that blacks are higher.
Take a look at every single black NFL QB's stats from the age of 23-28. Then look at those same stats 28 onward. I guarantee the VAST majority will decline HEAVILY because they are no longer as nimble as they once were. They can't throw the ball because they relied so much on their athleticism that they didn't develop a solid passing game.
Ohhh see I know what you're going to come back with- How many black QBs are there in the NFL compared to white QBs... so how can it be fair to compare superbowl wins? Well there's my point exactly. How many college black QBs are there? Look at the ratio. Then look at the ratio of NFL black Qbs. There is your proof
If he plays about 5 more years, it's conceivable that he'll be top 10 all-time in passing yards and TDs... you don't think that deserves a spot in the hall?
Vinny Testaverde is in the top 10 in both of those categories. Would you put him in the Hall?
VERY

What's so ridiculous is that people assume he continues his career averages... he's on a decline with his numbers! He is most likely out of PHI this offseason, and where does he go? Well there's only a limited number of possibilities:
DET: Not really conducive to good numbers, though at least he has an offensive weapon
CHI: As Charles Barkley would say, just turrable, turrable... Not to mention Orton is looking very very good there right now.
MIN: Berrian much of a better target than Curtis? Not really. One offense centered around the run to another... not much of an upgrade.
HOU: I highly doubt they sign him, but they need a QB so maybe... his best chance at putting up good numbers but I don't think they sign him.
KC: Thigpen looks great, I doubt they go after a vet
TEN: Possible if Collins retires and if Young isn't ready. They might see it as a chance to mentor the young overrated QB with an older overrated QB. But again, no real great WRs
TB: I'm sure they'd have some interest. An offseason doesn't go by where they try and acquire the rights to another QB.
Bottom line is that PHI is possibly the best team he'll ever play on, and he STILL isn't posting HOF numbers. He's been in the league for 10 years, if he hasn't convinced us by now that he's a HOFer, he never will. You can't have 2 great seasons to finish your 14 year career and expect to make it to the HOF...
You could add St. Louis, SF, and Ariz if Warner retires to the mix. Yeah, so only 1/3 of the league would be interested. Many of them are very solid teams. What was your point again?
St. Louis after they signed Bulger to a hefty deal? The coach got fired for benching him for one game. AZ spent a high 1st round draft pick on a QB... sure he hasn't been ready and has shown to be nothing but a bust- but anyhow why go after a QB who can't throw when you've got WRs who love to stretch the field? AZ has bigger problems than QB, even if Warner retires. SF is awful. Again, a downgraded offense.1/3 of the league is interested... "many" of them are solid teams? No. Of that entire list AZ, TN and TB are the only solid teams, and they are the 3 least likely to go out and spend bank on a QB. You think AZ, possibly the cheapest franchise out there, wants to go spend money on a QB like McNabb? TB has bigger problems than QB, and with all the grief they've taken in the past couple years for stock piling QBs I don't expect them to go out again and grab another couple. And TN will probably pass the reins onto Young if Collins retires... they won't go out and spend lots of money to rent McNabb for a year or two when he'll command a hefty contract for many years.
Honestly chances are he signs with MIN, who isn't a very solid team. They have plenty of holes. It's a mirror image of PHI (surprise surprise their coach was at PHI).
My point is people think he's going to go into FA and sign with the Colts or the Patriots... all the good teams are taken. What's left over is the bad to mediocre teams that will actually be a step down for him. In order for him to be considered for the HOF, he needs to have an amazing final 5 years or so of his career as well as win at least one superbowl to prove he can hack it.
He needs to focus first on finishing games without panting for air, then he can look towards the HOF
