Looking at the stats for the finalists for the Manning Award, I would say Will has as good of numbers as any however I don't think he'll win it. I would lean towards Stroud or Pickett winning just based on numbers although it doesn't say if it factors quality of opponents. It also tends to go to the Heisman winner, if the Heisman winner is a quarterback. Here are the stats for this year's finalists. Will is first in completion percentage and tied for second in yards.
