The Buffalo Bills can't stop, won't stop.

They made another trade today, and this one has more turns than the hedge maze in "The Shining."

The Bills sent a conditional 2015 fourth-round draft choice to the Philadelphia Eagles and swapped this year's seventh-round slots for backup running back Bryce Brown.

The conditional pick is based on what the Bills acquired from the San Francisco 49ers for Stevie Johnson. If that becomes a third-rounder, then the Bills will instead give the Eagles a 2016 fourth-round pick.

And the pick the Bills send to the Eagles will become a 2016 third-rounder if Brown hits certain rushing incentives.

Brown is entering his third NFL season. The seventh-round selection from Kansas State played in all 32 of Philadelphia's games, starting five.

He rushed for 564 yards and four touchdowns as a rookie. In his first two career starts, he ran for 178 yards and 169 yards, with two touchdowns in each.

Brown ran for 314 yards and two touchdowns last season.
