Here are our selections for the 2015 ESPN.com All-Big 12 first team. We'll unveil our All-Big 12 second team on Thursday.
Offense
QB Baker Mayfield, Oklahoma: Mayfield piloted the Sooners to a Big 12 title and College Football Playoff bid with 3,809 total yards, 42 touchdowns and lots of memorable heroics.
RB DeAndre Washington, Texas Tech: The do-it-all senior back racked up a Big 12-best 1,759 yards from scrimmage and 16 scores.
RB Samaje Perine, Oklahoma: The Sooners’ bowling ball of a back shared carries and still managed to rumble for 1,291 rushing yards and 16 total TDs.
WR Corey Coleman, Baylor: A Biletnikoff Award finalist and one of the nation’s most freaky talents, Coleman led all FBS receivers with 20 TD catches.
WR Josh Doctson, TCU: Doctson finished No. 1 nationally in receiving yards per game (132.7) despite his wrist injury and broke most of TCU’s season and career receiving records.
WR Sterling Shepard, Oklahoma: Shepard will finish as inarguably the No. 2 receiver in school history after an impressive 1,200-yard, 11-touchdown senior season.
OT Spencer Drango, Baylor: The leader of the Big 12’s best offensive line is an Outland Trophy award finalist and could be an All-American for a second straight season.
OT Le'Raven Clark, Texas Tech: The giant mauler at left tackle was dominant once again this season and has never missed a start in 50 consecutive games.
OG Nila Kasitati, Oklahoma: One of the nation’s more underrated linemen helped OU average 300 rushing yards over its last seven games.
OG Blake Muir, Baylor: Muir developed into a powerful, reliable left guard who graded out as well as Drango throughout the season with 38 knockdown blocks.
C Tyler Orlosky, West Virginia: Orlosky broke out as WVU’s best, most consistent lineman and paved the way for the Big 12’s No. 2 rushing offense.
AP Jakeem Grant, Texas Tech: The 5-foot-6 menace put up more than 1,200 yards on offense, had nearly 1,000 yards on kickoff returns and scored TDs four different ways: receiving (7), rushing (2), kickoff return (2) and passing (1).
K Jaden Oberkrom, TCU: The best kicker in school history hit 17 of 21 field-goal attempts, was perfect from 50-plus yards and should break the Big 12 record for career field goals.
KR Morgan Burns, Kansas State: A true game-changer on special teams, Burns leads the nation in both kick return yardage (1,047) and kick return TDs (four).
Defense
DE Emmanuel Ogbah, Oklahoma State: The Big 12’s premier pass-rusher ranks No. 4 in FBS in sacks with 13 and logged a league-high 17.5 tackles for loss.
DE Charles Tapper, Oklahoma: Tapper recorded seven sacks and four forced fumbles and was a monster for OU during the stretch run to a Big 12 title.
DT Andrew Billings, Baylor: Big 12 coaches say he’s the best nose tackle they’ve seen in a long, long time, and Billings lived up to the hype with 14 tackles for loss.
DT Hassan Ridgeway, Texas: He battled injuries early and late in the season but still caused problems, finishing with 3.5 sacks and a fumble return for a TD.
LB Eric Striker, Oklahoma: One of college football’s great leaders and characters was also a deadly edge rusher with 16 tackles behind the line (14 in Big 12 play) and 7.5 sacks.
LB Nick Kwiatkoski, West Virginia: The Mountaineers’ leading tackler for a third consecutive season also chipped in three INTs, three sacks and seven pass breakups.
LB Dominique Alexander, Oklahoma: He emerged as one of the league’s best all-around defenders and was a critical cog at inside linebacker with a team-high 91 stops.
CB Jordan Thomas, Oklahoma: Zack Sanchez gets more pub, but Thomas stepped up and showed star potential as a sophomore with five interceptions.
CB Daryl Worley, West Virginia: He had a few rough stretches in conference play but made big plays, too, including six INTs and 12 pass breakups.
S Derrick Kindred, TCU: His veteran leadership through all of the Frogs’ lineup changes proved just as valuable as his 79 tackles and two picks.
S Jordan Sterns, Oklahoma State: Sterns led a stout Oklahoma State defense with 103 tackles and nabbed two INTs, including the game-clincher at Iowa State.
P Nick O'Toole, West Virginia: He helped WVU flip field position with a Big 12-best average of 45.6 yards per punt, including 40 percent downed inside the 20.
PR KaVontae Turpin, TCU: The true freshman was one of Big 12’s fastest players, dazzled in space and averaged 10.6 yards per punt return, including a 49-yard TD.
