Add rookie free agent FB Corey White from UAB to the list of potential backup or even starting players at fullback in 2007 because the Packers will sign him after he had a tryout last weekend. There's not much to get excited about with him. He will convert from running back to fullback after battling injuries throughout his senior season. Unfortunately he wasn't much of a receiver in college.
However it's hard to tell whether Mike McCarthy likes to use the fullback in the passing game or not. Were there few passes thrown at FBs Brandon Miree and William Henderson last season because McCarthy doesn't like using fullbacks in the passing game or because they weren't very good? If they're only used as blockers that's too bad because it gives QB Brett Favre fewer passing options and makes it more likely he will try and force the ball to one of his wide receivers.
6th round FB Korey Hall is converting from linebacker to fullback so he is probably ahead of White and behind Miree. But since Miree was signed onto the Packers practice squad only last September after Denver waived him, he's no guarantee to make the roster in 2007 either. The Packers will probably keep at least one of the three, if not two of the three, but might keep an extra tight end instead of a backup fullback. It's possible 7th round pick RB Deshawn Wynn is converted to fullback too, but at the moment he remains at running back.
It was a bummer that Wisconsin QB John Stocco won't be offered a contract, but he was a longshot to beat out QB Jerry Babb since the Packers had already signed Babb to a rookie free agent contract while Stocco only had a tryout. Hopefully he has better luck with the NY Giants.
