The Buffalo Bills plan on having at least three rookie starters on defense this season.

"At least three," Whaley said. "Shaq Lawson is going to walk in off the bus starting. Reggie Ragland and then Adolphus Washington -- all three of those guys will start right off the bus. And we're excited for some guys from the fourth through sixth rounds that will contribute for us."

The Bills selected Lawson 19th overall and is expected to replace Mario Williams on their defensive line.

Ragland went 41st overall at linebacker and Washington was picked 80th to give Rex Ryan another option on the defensive line.
