'To make the major investment required to obtain Revis, who will be 30 when training camp begins, the Bills would likely be inclined to unload the cornerback with the largest cap number for his position on the team, McKelvin, who is going to be 30 when the season begins. Graham’s number isn’t far behind and he’ll also be 30 when training camp starts, but the length of his deal and resulting cap acceleration make it harder for the Bills to cut ties with him.'
