Bills sign RB Mike Gillislee, three others to contract extentions

When LeSean McCoy went down with a knee injury in Week 15, it was Karlos Williams and Mike Gillislee -- two relatively unknown backs -- that stepped up in his absence. The picked up right where Shady left off and performed admirably, helping the Bills lock up the rushing title for Buffalo.

On Monday, the Bills rewarded Gillislee and a handful of others. The team announced that they have signed Gillislee, cornerback Mario Butler, wide receiver Greg Salas and punter Colton Schmidt to contract extensions.
