The top four quarterbacks on NFLDraftScout.com's board are not throwing passes at the 2012 Scouting Combine.
Stanford's Andrew Luck (own choice), Baylor's Robert Griffin III (own choice), Texas A&M's Ryan Tannehill (foot) and Arizona State's Brock Osweiler (unknown) have each said they won't be throwing at the Combine.
Highly regarded quarterbacks electing to hold off until their Pro Day is nothing new, of course. Often the reasons given by these quarterbacks as to why they'd rather wait until their Pro Day is the fact that they'll be throwing to their own receivers in the surroundings they've grown accustomed to.
NFLDraftScout.com, however, was told of another reason why quarterbacks may want to wait until their on-campus workouts. The high-level source used Cam Newton's erratic performance during the Combine throwing session last year as an example.
"Last year [scouts] didn't sync the QB drop and the wide receiver pattern. For example, [Newton] was dropping five steps but the wide receivers were doing three step type patterns."
The miscommunication caused Newton's accuracy to appear to be inconsistent. He took the hit publicly for a mediocre performance and to his credit never said a word publicly about what may have been the biggest reason for it.
The Carolina Panthers obviously looked past the performance -- and considering the terrific rookie season Newton had in 2011, they were certainly wise in doing so.
