to me this article says Ray is slightly more physically impressive than Sam, and they both have had production on the field.

The difference is EVEN if one guy has those 20 extra tackles, tackles for loss, and sacks, one person is a 1st round talent that slid because of an off the field issue. The other guy had no off the field issue, yet in coming out slid all the way to the 7th Round.

If I give merit to the production disparity on the field, at MOST Sam should slide to the 2nd or 3rd round. But he almost went undrafted, as an SEC Defensive Player of the Year. There's no way he shouldn't at least be smelling an NFL roster.
