Most overpaid: Pears and Urbik. The Bills had problems on the right side of their line last season, where Urbik (right guard) and Pears (right tackle) were positioned. The pair of veterans both face stiff competition this summer, especially after the Bills drafted Kouandjio (second round), Richardson (fifth round) and Henderson (seventh round). In addition, Hairston looked to be pushing for a starting job during OTAs and minicamp this spring. Pears, 32, is in the final season of his three-year extension and the Bills can avoid paying his $2.75 million base salary by cutting him before Week 1. If Urbik loses his starting job, he'll be among the most overpaid Bills. He has three years left on his deal, meaning the Bills will have eat some money if they keep him on the bench or cut him, the latter of which is unlikely.

Most underpaid: Glenn. There's nothing that can be done about Glenn's contract until after this season, as he and the Bills will have to wait until after his third year to renegotiate his contract. He was arguably the Bills' best lineman last season, and with another strong season will be at the top of the list for an extension.
