Valdez is an interesting case: his arm length scared teams off during the draft process, but at 301 pounds with legendary gym strength (reported 405-pound bench presses), he's exactly the kind of space-eating anchor San Francisco's Wide 9 front wants inside. He was elevated from the practice squad again in late September, a sign the staff likes what they see even if it hasn't translated to a permanent roster spot yet.
Strengths: Elite raw power and leverage against double-team run blocks, which fits San Francisco's Wide 9 defensive front well.
Weaknesses: Short 31 1/4-inch arms limit his ability to disengage from blocks and he remains on a week-to-week practice-squad elevation basis.
