I just typed this all out from a magazine article as a response to another thread. I hate to waste all that typing for nothing so I decided to make a new post with the info.
I am still unsure who I think will be the better QB, but I found the numbers in this article very interesting. Forgive any typos I couldnt find a link so I typed it from the magazine.
Quoted From: "How Do you Seperate the Peyton Mannings from the Ryan Leafs"
ESPN NFL DRAFT GUIDE 2007
................ Peyton proponets argued that he was more mature and accomplished. Leaf Backers argued he had the stronger arm and more growh potential. But all the Colts really needed to know was four numbers: Manning started 45 college games, completing 63% of his passes; Leaf started 24 games, completing 54% of his passes. The future couldnt be more clear.
It's true: college satatistics really can prdict NFL performance. For our 2006 Pro Football prospectus, we studied 10 years' worth of drafts and discovered that the single greatest indicator of NFL success for QBs taken in the first 2 rounds is the number of college games they started. Phillip Rivers, for one, started 51 games at NC State. Mcnabb started 49 games and Carson Palmer started 45. On the flip side, bust-to-be Joey harrington (28), Jim Druckenmiller (24), and Akili Smith (19) had relatively little starting experience.
The other inportant predictor is completion percentage. Ben Roethlisberger completed more then 65% of his college passes. Rivers completed 64%. Both Manning brothers had completion percentages above 60%, as did Drew Brees, Matt Leinert, and Vince Young. Leaf and Druckenmiller, on the other hand couldnt complete 55% of their passes. Harrington, Smith and Cade McNown barely did. Kyle Boller didnt even complete half of his college passes.
What about the QBs who will go early in the 2007 draft? Brady Quinn started 45 games and completed 58% of his passes, almost identical to McNabb and halfway between Palmer and Jay Cutler. JaMarcus Russell completed 62% of his passes but had just 29 starts. Those numbers are similar to Kellen Clemens' and Rex Grossman's. .........................
