There’s no denying the impressive physique and workout numbers that have been posted by Ohio State defensive end/linebacker Vernon Gholston.  But some league insiders are concerned that Gholston might be this year’s Mike Mamula.

Mamula, you might remember, was a defensive end who rocketed up the draft board based on incredible pre-draft numbers.  The Boston College product made it all the way to No. 7 in 1995, jumping past guys like Joey Galloway and Warren Sapp and Hugh Douglas and Ty Law.  But Mamula was a bust as a member of the Philadelphia Eagles, and he has long since been out of the league.

As to Gholston, a league source tells us Gholston simply isn’t memorable when watching game film.  As the thinking goes, if he were a dominant player at the college level, he would be showing up in the thick of things on a continuous basis.  Per the source, he simply doesn’t.

We’ve recently heard that the Raiders could be targeting Gholston with the No. 4 overall selection.  But plenty of league insiders don’t see him being a top-five selection.
