Our weekly effort to identify one player poised for a breakout on each Big 12 team got a few right last week -- Cory Morrissey was huge for Iowa State, Brandon Sheperd scored again -- but we can do better, even on a bye-heavy week. Here are five players worth keeping an eye on in Week 4.

Kansas State WR Tyler Lockett: If some people still don't know, they're about to find out. Lockett was better than ever in big ballgames last season against Oklahoma, Texas and Michigan. He's going to show up tonight against Auburn, line up all over and attack an Auburn secondary that's missing a starting safety. Lockett has All-America talent and this is another big chance to prove that.

Oklahoma RB Samaje Perine: Now is the freshman's time to shine. Perine, a freakish 243-pound power back, will share the load with Alex Ross now that Keith Ford is sidelined and could have a big night in Morgantown. He's a hard dude to bring down and his speed is probably underrated. He should find the end zone a few times against West Virginia.

West Virginia CB Ishmael Banks: After missing West Virginia's first three games due to an academic suspension, "Icky" will be back on the field at a critical time, right as Daryl Worley is suspended indefinitely. A senior who started every game last season, Banks will have to be one of the DBs responsible for stopping Sterling Shepard and trying to make this explosive Oklahoma offense more one-dimensional.

Kansas QB Montell Cozart: It's a gut-check week for Cozart, who completed just 11 of 27 passes against Duke, couldn't get the ball to Nick Harwell and looked far too nervous under pressure. Charlie Weis' staff is committed to making this work with Cozart, but you can't get the yips in a big game like that. He needs this Central Michigan game to be his bounce-back performance.

Kansas State DE Ryan Mueller: Not just because Mueller is one of K-State's best, but because of this particular matchup. Playing against a team that has mastered the zone read, the pop pass and all sorts of option wrinkles creates a real challenge for any defensive end. K-State's front seven must maintain gap integrity, and Mueller in particular has to make responsible decisions and get tackles for losses at the mesh point when he's in position to make a play.
