Bills sign QB A.J. McCarron (2 years, $10 million): A+ Grade How did this happen? In an offseason in which Sam Bradford got $20 million for a year, Josh McCown received $10 million for a season, and Case Keenum obtained $18 million per year, A.J. McCarron somehow was stuck with far less money than all three. McCarron, with this deal, is set to earn as much as Chase Daniel, which is unbelievable. In the Daniel write-up, I wrote that average backup quarterbacks should earn $4-5 million. McCarron is certainly not a typical No. 2 signal-caller. He's a premium reserve quarterback; if not a below-average starter. I still expect the Bills to select a quarterback in the opening round, as I detailed a potential NFL Draft trade with the Giants that could occur. McCarron would provide insurance just in case Buffalo couldn't make the move. He would also be able to start while the rookie signal-caller is being developed. This is an outstanding signing that is worthy of an A+ grade.
