Blake Bell, Oklahoma's 6-foot-6, 263-pound junior, was a short-yardage specialist behind Jones. Bell ran 102 times for 24 touchdowns the past two seasons, and then was one of three quarterbacks to throw touchdown passes in the Sooners' spring game this month.
"He's always been able to throw the football well. Blake throws a great deep ball,'' Sooners coach Bob Stoops said.
Kansas State returns all five starters on the offensive line. As for who they'll be blocking for this season, Daniel Sams, the primary backup for Klein, and highly touted junior college transfer Jake Waters are the leading candidates.
Coach Bill Snyder said there "is no clear-cut No. 1'' and that both are getting equal snaps with the first- and second-team offensives this spring.
West Virginia also had a 50-50 split of reps at the quarterback spot this spring between Paul Millard and Ford Childress while trying to determine who succeeds Smith.
"Wide open, man,'' West Virginia coach Dana Holgorsen said. "We will kind of encourage them to get out there and throw with the guys and study film for the next 3 1/2 months. Then get the race kick-started back in August to see whose' made the most progress. We don't have to make the decision now.''
Kansas has Jake Heaps, who was a freshman starting quarterback for BYU and can now play for the Jayhawks after sitting out last season following his transfer. He played 22 games for the Cougars, including 16 starts.
Texas Tech, with former standout quarterback Kliff Kingsbury now its coach, has to replace senior Seth Doege. Sophomore Michael Brewer and freshman Davis Webb, who went through spring drills after graduating from high school in December, combined for 506 yards passing and three touchdowns in the Red Raiders' spring game.
Bryce Petty gets his chance as Baylor's starter after being on the team with Griffin and then Florence the past three years, including a redshirt season.
Sophomore Sam Richardson got to start a couple of games at the end of last season for Iowa State, who had a senior starter until that point.
"Quarterback play certainly has not gotten us to a position where we can win the nitty-gritty games. That's a position that every program looks for a difference maker,'' Rhoads said. "That's a position we have to get better play out of to get us in the top half of the Big 12 conference.''
