Luck is part of football success, sometimes as important a part of winning as corned beef, cabbage and green beer are to St. Patrick's Day.
Here are several Big 12 coaches and players who could stand to benefit from an extra four-leaf clover or two to improve their good fortune this season.
Dan Hawkins, Colorado: No Big 12 squad faced more injuries last season than Hawkins' Buffaloes. Losses in the offensive line to Ryan Miller and Maxwell Tuioti-Maxwell and Rodney Stewart's broken fibula helped cripple the Buffaloes' title hopes. Another similar run of injuries could put Hawkins' job in jeopardy.
Sam Bradford, Oklahoma: A veteran offensive line helped power Bradford to the Heisman Trophy last season. How much different will it be in 2009 with four new starters along the offensive line? Bradford hopes he won't have too much green in the form of grass stains on his jersey from opposing team's hits, as his young protectors must grow quickly into their new roles.
Art Briles, Baylor: The only coach in the conference who makes green part of his game-day garb could use some good fortune to hope nothing happens to Robert Griffin. If Griffin can stay healthy and productive, the Bears can contend for a bowl berth. If not, it will be another long season in Waco.
Jordan Shipley, Texas: Injuries have cost him two seasons of eligibility. When healthy, he plays like one of the most explosive wide receivers in the nation. He will be particularly important this season as Colt McCoy's veteran receiving threat and a potential kick-return menace every time he touches the ball. Just ask Oklahoma.
Barry Turner, Nebraska: The Cornhuskers' top pass-rushing weapon sustained a broken leg in the second game last season and missed the rest of the season. His return and good health could provide a much-needed outside pass-rushing threat for the Cornhuskers and take some of the double-team pressure away from massive defensive tackle Ndamukong Suh.
