A new season is upon us, meaning it is time to peer into the crystal football and forecast what lies ahead for Big 12 teams.But in a crowded title race, with more contenders than pretenders at the conclusion of fall drills, there is a lone point of clarity: Some under-the-radar player is going to emerge and tip the scales in the direction of his team by the decisive first Saturday in December.Breakout newcomers emerge every year. But with uncanny Big 12 balance expected in this year’s race, their 2013 impacts mean more than in most seasons.Until games begin this weekend, most will remain fall-camp phenoms known only to their coaches and fan bases. But someone from this list has a great chance to emerge as the Big 12’s best surprise of 2013: Robbie Rhodes, Baylor, WR: The elusive freshman from Fort Worth Southwest has not disappointed coach Art Briles, who called him the “best receiver in America” among 2013 signees. Asked about Rhodes’ ability to make an immediate impact, Briles said: “Yes, sir. He will contribute on the 31st of August. He is a dynamic guy.” Other notable Baylor newcomers: DE Shawn Oakman (6-foot-9, 270 pounds), a transfer from Penn State, and DT Andrew Billings (6-0, 305), a freshman from Waco who set a national high school powerlifting record in March. Trevor Knight, Oklahoma, QB: The redshirt freshman from San Antonio Reagan edged junior Blake Bell, the team’s backup the past two seasons, for the Sooners’ starting job in fall camp. A dual threat whom Oklahoma coaches compare to Texas A&M’s Johnny Manziel, Knight threw for 2,092 yards and rushed for 943 in his senior season in high school. Other notable new Sooners: DT Quincy Russell, a junior college transfer, and CB Cortez Johnson, a transfer from Arizona. Ben Grogan, Oklahoma State, K: In a league where lots of close games are expected, the freshman from Arlington Martin projects to be instrumental to the Cowboys’ title hopes. A Class 5A first-team all-state performer last season, Grogan won the battle to succeed the departed Quinn Sharp as the Cowboys’ kicker on Aug. 10. Ja’Juan Story, TCU, WR: A top-50 national signee with Florida in 2011, Story (6-4, 208) has yet to play in a college game. He redshirted in 2011, then transferred to TCU and will make his college debut Saturday night against LSU at AT&T Stadium in Arlington. Desmond Harrison, Texas, OT: Last season’s top-rated, junior-college offensive tackle by 247Sports.com, Harrison (6-8, 310) has been impressive in fall drills after getting eligibility issues clarified last week. He will play Saturday and could soon emerge as the starter at left tackle, where current first-teamer Donald Hawkins is being double-trained at guard and tackle. Asked about Harrison, coach Mack Brown said: “He’s so talented, it’s unbelievable. He needs to be out there and learn, so he’ll be ready to go by the time we get into Big 12 play.” Jake Waters, Kansas State, QB: The 2012 national player of the year in the junior college ranks won a battle with Daniel Sams, last year’s backup quarterback, to replace the departed Collin Klein. Kansas State coaches have said both will play in Friday’s opener against North Dakota State. But the focus will be on Waters, who produced eye-popping JC stats: a 73.3 completion rate, 3,501 passing yards and a 39-3 ratio of TD passes to interceptions.Among teams not expected to push for more than down-the-line bowl berths, Texas Tech will rely heavily on a true freshman quarterback (Davis Webb or Baker Mayfield) until sophomore Michael Brewer returns from a back injury and Iowa State will turn to sophomore Sam Richardson, a third-teamer most of last season.But in terms of immediate impact, the nation’s sweetest skill-position transfer tandem belongs to West Virginia. Only the Mountaineers have the potential to turn to a quarterback/running back combo that suited up for two different FBS schools in 2012.Running back Charles Sims, Houston’s leading rusher last season (851 yards, 11 TDs), earned preseason Big 12 Newcomer of the Year accolades from media members after joining the program in July. Quarterback Clint Trickett, Florida State’s backup to E. J. Manuel the past two seasons, arrived in May and could win a tight battle with Paul Millard to be the team’s starter. Both Sims and Trickett graduated from their previous schools to earn immediate eligibility at West Virginia this season.
