I think its pretty hard to put any of the young guys in the top 2 tiers, or roughly the top 10. There is no reason to doubt the guys at in the top 10 will continue to perform well for years to come, and they've all done it multiple times. The young guys may very well join the list of elites, but what is the upside to drafting them? They'll be very fortunate to match guys like Brady and Brees for the next 5 years.
1. Rodgers
2. Brady
3. Vick
4. Rivers
5. Manning
6. Brees
7. Romo
8. Roethlisberger
9. Schaub
10. Ryan
11. Manning
12. Freeman
13. Bradford
14. Flacco
15. Cassel
16. Orton
17. Stafford
18. Cutler
19. Kolb
20. Sanchez
I realize you're a Packer fan, but holy jeebus.

Below Orton and Stafford? C'MON MAN!
Since he's been a Bear, Cutler has 10 games where he didn't throw a TD pass. Clunkers. The Bears now understand what they have in Cutler. A rocket armed, pea brained Qb. If he throws it more than 30 times a game, he's most likely gonna lose the game for you. Starting week 10, Cutler attempted less than 27 passes 6 of 7 weeks. I just don't think they are gonna let him pass it enough to be a reliable top 10 guy. The Bears formula for winning is defense and special teams. I don't see that changing anytime soon.
Through the first 12 weeks, Orton was top 3. It will obviously depend on where he goes, but I'd think SF or ARI will make a play for him. They both have nice receiving options already in place.
As for Stafford, injury is the obvious concern. I think his upside is as high as anybody not named Vick. So yeah, I'd take him ahead of Cutler.
