Chances are, Stanford's defensive backs appreciate the tutoring because Shaw still is in the process of hiring a secondary coach. Despite the loss of starting free safety Ed Reynolds, the secondary should be a team strength this fall. Strong safety Jordan Richards is a star, and Stanford returns both starting corners, Alex Carter and Wayne Lyons. Perhaps not coincidentally, Carter (6-foot, 200 pounds) and Lyons (6-1, 196) are "big" corners -- the kind many NFL teams crave after watching Sherman (6-3, 195) and his secondary mates shut down passing attacks on a weekly basis during their Super Bowl-winning season.
