Based on your logic and your so called expertise in Basketball. Why aren't there more white PGs in the NBA. Also, let's face it until 10 years ago, black qbs weren't even given a chance. They were moved to WR.
Yes, the 4 qbs you listed are the top qbs, but then how do you explain the following:
Joey Harrington
David Carr
Charlie Frye
Andrew Walter
Why aren't these guys stars, they haven't been hurt, they are pocket passers?
Are you serious. geeze. White point guards? Well, lets see. for one, that is basketball and not football. second, thats all about quickness, athleticism, leaping ability, etc. Thats what homeboys excel at. Thats why they play basketball. OOverall, they are just more athletically gifted than white people. sure there are some exceptions. But having an athletic running quarterback is slightly different than having a point guard of any color. We are talking franchise guys here at both positions but guess what injury rate will be higher.
Why aren't the guys you listed franchise quarterbacks? Ummm, why aren't I? i'm white. Why aren't you? I'll say this, Tim Couch could have been a true franchise quarterback coming out if he had real coaching, just decent recievers, decent luine, and decent RB. The Browns have been an absolute disaster since returning to the league. But I don't need to debate that but poor coaching stability, Kevin Johnson was their #1 receiver and William green ended up being a bust.
Why aren't their white running backs? You should know the answer. Their are fundamental differences in blacks and whites. People need to learn that and accept it.
Here are some FACTS:
Vick: Misssed 1 whole season and a couple games here and there: broken leg from running
Culpepper: torn ACL from RUNNING
McNair: when 8is he not hurt. he's missed the equivalent of at least 2 seasons
McNab: See McNair: Seems he's hurt almost every year
Vince Young: Will be hurt. Just a matter of time especially since he is not as fast as others and just more glides when he runs. i predict he will miss 2 full seasons
Given its a small sample size, but that is 100% of the black quarterbacks. And even if you throw Leftwich in there who is a pocket guy and slow delivery, he missed basically all of last season plus has proven not to be a franchise guy.
