The Raiders have begun attacking the waiver wire for much needed roster depth with their first signing of former Redskins OT Willie Smith. The 6' 6", 310 lbs offensive tackle with 2 years of NFL experience signed by the Redskins as a UDFA out of East Carolina. Smith started the few games for Washington last season. Scouts say that he has good size and strength and above-average athleticism.His effort is good but he lacks consistent technique and as both a run and pass blocker. Smith is raw and needs time to develop. Maybe the ZBS will do him well and with the way Barksdale has looked, this is a good signing.
