ALAMEDA _ Raiders linebacker Ray-Ray Armstrong is a legitimate NFL prospect from snap to whistle.
After the whistle has blown, the prospect has sometimes become suspect because of the occasional personal foul, scuffle or running verbal battle.
Last season, St. Louis Rams coach Jeff Fisher abruptly cut Armstrong after a personal foul despite being a core special teams player. A waiver claim by the Raiders, Armstrong flashed the same kind of skill he did with St. Louis _ he even had three late-season starts _ as well as the penchant for penalties.
Fast forward to the Raiders mandatory minicamp, where Armstrong has been getting plenty of work as the first team weak side linebacker as incumbent Sio Moore slowly works his way back on the field following offseason hip surgery.
