Tough year for ex-Cowboys in Chicago

News of Chicago Bears receiver Sam Hurd's arrest will generate all kinds of salacious news coverage given the amount of drugs he allegedly committed to purchasing from an undercover officer. But assuming Hurd has played his final game for the Bears, it's also worth noting how little the Bears have gotten from the trio of former Dallas Cowboys they signed in the free-agent scramble of 2011. A closer look:

Sam Hurd

Contract: Three years for about $4 million, including a signing bonus of $1.35 million

Performance: Hurd has caught eight passes for 109 yards and been involved in eight tackles on special teams over 12 games.

Receiver Roy Williams

Contract: One year for $2.5 million

Performance: He has caught 26 passes, including one for a touchdown. ESPN Stats & Information conservatively lists him with four drops.

Marion Barber

Contract: Two years with compensation of $2.5 million in 2011.

Performance: He has 389 yards and six touchdowns in 10 games this season. Two late-game mistakes last Sunday at Denver doomed the Bears' chances to win.
