The first news of the Raiders hosting a draft prospect for a visit comes in the form of mammoth nose tackle Josh Chapman out Alabama according to CBSsports.com. The Raiders look to be switching to a 3-4 base defense and the addition of a guy like Chapman would help them accomplish it.

Chapman had surgery to repair a torn ACL last January and is slated as a round 2-3 prospect in the upcoming draft. If not for the injury and the surgery to repair it, he would undoubtedly be a more highly rated prospect. The health of that knee is part of what the Raiders would like to see first hand.

The 6-1, 315 pound lineman was the anchor Alabama's stout defensive front and was a key to the Crimson Tide's run-stuffing ability. He started all but one game (due to injury) at nose guard in his senior season and 25 overall during his career at Alabama. He was named honorable mention All-American by Pro Football Weekly, second-team All-SEC by league coaches and the Associated Press.

As a display of his worth to the Alabama defense, the one game he missed as a senior, Georgia Southern ran for 302 yards on them.
