Running back Chris Carson could hold the key to Oklahoma State’s offense, wide receiver DeDe Westbrook could take Oklahoma’s new spread attack to another level and defensive tackle Demond Tucker could provide much-needed strength in the middle of Iowa State’s defense.

That trio is among the nine ESPN Junior College 50 recruits who signed with Big 12 schools and have the potential to become household names in the conference this fall.

Which ESPN JC 50 newcomer do you expect to have the biggest impact?

Carson was a late addition to the Cowboys' signing class as OSU looked to secure a backfield mate for quarterback Mason Rudolph. The No. 12 player in the ESPN JC 50, Carson brings good size (6-foot-2, 210 pounds) and the ability to be a workhorse for Mike Gundy’s program.

Westbrook is already on campus and participating in spring drills with the Sooners. The No. 14 player in the ESPN JC 50 combines quickness and speed with good size (6-1, 175), which makes him a candidate to excel in the slot or on the outside in Lincoln Riley’s offense.

Rasul Douglas will add to a talented West Virginia secondary in the summer. The No. 23 player in the ESPN JC 50 has the size (6-2, 200) and athleticism to be a versatile asset for WVU’s defense, with the skills to play cornerback or safety.

Tucker was a much-needed addition for the Cyclones defense. After Iowa State struggled with its depth and production along its defensive front in 2014, Tucker is participating in ISU’s spring practices with a eye on making an major impact this fall. His quickness could help him become a disruptive force for the Cyclones defense.

Five other ESPN JC 50 signees could have a similar impact in the Big 12. Cornerback Will Johnson (No. 15 in the ESPN JC 50) is already impressing during the first few practices at OU, and the Sooners secondary is looking for playmakers heading into the fall.

Offensive tackle Maurice Porter (No. 31 in the ESPN JC 50) could add additional depth for Baylor’s offensive line when he arrives in the summer.

Guard Jamal Danley (No. 39 in the ESPN JC 50) is going through spring drills with OU as he battles to make an impact on a Sooners offensive line that must replace four starters.

Texas is hoping Quincy Vasser (No. 45 in the ESPN JC 50) can help lessen the loss of Cedric Reed at defensive end.

Motekiai Maile (No. 49 in the ESPN JC 50) could help replace James Castleman in the interior of OSU’s defense, helping free opportunities for returning Big 12 Defensive Lineman of the Year Emmanuel Ogbah.
