Even with the starting five offensive linemen for the Raiders looking like one off the better units in the NFL, they could still be looking to bulk up depth and for the long term. Prospect visits are often a great way to uncover some hidden talent. Tuesday University of Houston offensive lineman Alex Cooper paid the Raider a visit, according to Aaron Wilson of the Houston Chronicle.

Cooper is a versatile lineman, which could make him attractive to a team like the Raiders that place great value in versatility. After starting all season at right guard as a junior, the 6-4, 305-pounder started every game last season at left tackle, right tackle, and right guard for the Cougars and was named second team all conference.

He is not currently projected as a draftable player, but you never know if a player visit can raise his stock with that team. That's what the Raiders were looking to find out.
