Important now for Steelers to retain WR Wallace

The Steelers' announced release of WR Hines Ward means they're likely to keep Pro Bowl WR Mike Wallace. It's doubtful Jerrico Cotchery will return as a No. 4 WR, but still possible. Whatever, Ward's exit means the Steelers need to sign a veteran No. 4 receiver and/or draft one. The affect on the locker room? That won't be known until fall.
