DALLAS, TX -- It looked like a back-handed way for the Bengals to execute the second player-for-player trade of 2009:  pick up released former Dallas safety Roy Williams, then release safety Marvin White, who then got picked up by the Cowboys.

Unfortunately for White, it didn't work out that way for long.  On Saturday, the Cowboys released him to make room for promoting running back Chauncey Washington from the practice squad.

For those of you who don't remember, Marvin White is the hard-hitting safety from TCU who delivered several punishing blows to opposing ball-carriers.  Much to his chagrin, however, those hits weren't always accompanied by an actual tackle, as displayed in this 2008 preseason game against the Green Bay Packers...

White managed to hit Packers WR James Jones so hard that his helmet flew off, but Jones stayed on his feet and scampered into the end zone untouched after the hit.

One can only guess that the ol' tackling skills (never to be confused with "numb-chucks" skills, computer hacking skills...) did not improve for Marvin White during his brief stint with the Cowboys.  We hope he catches on with another team who needs defensive help.
