Texas Tech has a lot of questions to answer on the offensive line this spring, but the Red Raiders hope they have a rock at one important position. Not surprisingly, new coach Kliff Kingsbury has penciled in standout sophomore Le’Raven Clark at left tackle after his impressive 2012 season. There could be some adjustment, though, since this will be Clark’s first experience at the spot as a Red Raider. He spent all of last spring at right tackle and then started every game last season at right guard.

Texas Tech released its spring roster Thursday. The key developments: ■ Defensive tackle Michael Starts, linebacker Daniel Cobb and safety Chris Yeakey aren’t listed.  Cobb graduated at mid-term, a Tech spokesman said, and left the program with a year of eligibility remaining. Yeakey said near the end of last season he wanted to petition for a sixth year because he’d lost two seasons to injuries. He made five tackles in 11 games, mostly playing on special teams.

The call came in to the New York Jets offices last season, a few days before New York was scheduled to play at Tennessee. Jets coach Rex Ryan and his assistant Laura Young pulled aside Mike Smith to pass along a warning to the exuberant young defensive assistant. “They said, ‘Hey, you’ve got to stay off the field,’” Smith recounted. “‘The head referees are calling and complaining because you’re halfway out on the field every time somebody makes a big play.’”
