The interesting thing to me about this little debate is that only one season is being considered here. Russell had an outstanding season last year. There is no doubt of that but I don't think you can just turn a blind eye to previous seasons played. I also think people need to have a bit of a reality check in regards to the seasons each player had last year.
Russell posted the following numbers last year.
342 Atts. 232 Comp. 67.8 Comp% 3129 yds 28 TDs 8 INTs
Quinn posted the following numbers last year.
467 Atts. 289 Comp. 61.9 Comp% 3426 yds 37 TDs 7 INTs
Each played in 13 games. Now, I'm no rocket scientist but the only stat that Russell was better in is his completion percentage which is significant. However, Quinn clearly out produced by a long way in TD to INT ratio which, IMO, is the most important stat a QB has. Now some may say W and L are more important and I would be hard pressed to disagree with that but in this situation, all things, (talent wise) are not equal.
If you look at career numbers, it's no contest. Brady is far superior to Russell from a production stand point. Now, you might say that this is because Brady has been a 4 year starter and Russell has not. I think there is some merrit to that but it's not Brady's fault that he was good enough to start as a True Freshman while Russell was not. I just think you have to look at the whole body of work.
I'm also interested to know how you come up with a 267 QB rating.
