The Facts: The Bills signed Kolb to a two-year deal last March, but a second run in Buffalo is far from certain, according to his coach. "He's under contract and I'm not aware of really what exactly is going on right now, whether he's planning to come back, whether he's not going to come back," Doug Marrone said Friday. "I have not been informed of anything to that nature."

Diehards Line: In case you missed it, Kolb didn't even make it into the regular season in 2013. An August concussion landed him on injured reserve amid whispers that he was contemplating retirement. After suffering a string of head injuries, Kolb's once promising future is entirely up in the air and we don't expect the Bills to absorb his weighty $1 million roster bonus due next month. According to NFL.com, cutting the 29-year-old signal-caller would save $3.1 million against the cap. Besides, Buffalo has plenty of quarterbacks with Thad Lewis, Jeff Tuel and Dennis Dixon on the payroll behind starter EJ Manuel. In other words, the Bills won't be pushing for his return.
