Especially the flow of the game, the substitutions,” Bowlsby said. “With the speed of the game, it makes some sense.”Signing day Big 12 athletic directors remain undecided on whether to support a proposal for an early signing date in college football, as suggested by ACC administrators.The ACC suggested an Aug. 1 option, which has not gotten much traction with Big 12 officials. John Currie, Kansas State athletic director, made it clear he prefers keeping it on the first Wednesday in February.“We talked about it some. But I don’t perceive any extreme momentum for that,” Currie said. “For every argument for that, there is a big stack of arguments against it. I personally believe those decisions already are being made far too early by student-athletes, often to their detriment.”Texas Tech athletic director Kirby Hocutt, chairman of the NCAA football recruiting subcommittee, said additional discussions are slated at a June meeting. He said football coaches have yet to take a national position in favor or against the date switch.Governance changesBig 12 administrators spoke in favor of proposed NCAA governance changes that would allow more autonomy to schools from the five power conferences.Action on that front could be taken in August, including provisions that would allow athletes the full cost of college attendance, enhanced medical care and an opportunity to receive additional scholarship help after players have exhausted their college eligibility or left early for professional careers.Bolwsby said the 65 schools in the highest-profile leagues seek “a new covenant with today’s student” because NCAA rules have not evolved adequately to meet their needs over the past three decades.Texas President Bill Powers said: “There’s a wide consensus among the five conferences that we need to adjust to the times and the issues. We need some reform. How we go about it is the issue and we’re in discussions.”Bowlsby said he plans to seat a task force of Big 12 administrators to examine potential tweaks that league officials want to stress when more autonomy becomes a reality. TCU footballTCU athletic director Chris Del Conte said school officials are in negotiations with a Pac-12 school to finalize a home-and-home football series for the 2019 and 2020 seasons.He said he hopes to have an announcement next month.Tiebreaker tweakBig 12 officials have tweaked the wording in their football tiebreaker procedures to adopt the College Football Playoff rankings in lieu of the BCS standings to break multi-team ties in the league standings.Bowlsby said: “All it is is nomenclature. We struck the places where it said BCS and added … CFP.”Basketball changesBowlsby left open the possibility of having the Big 12 men’s and women’s tournaments in the same city in future years, but nothing is set.The tournaments have been held in different cities the past two years and the same will be true in 2015, with the women’s event in Dallas and the men’s event in Kansas City, Mo.Bowlsby also left open the possibility of starting conference play before Christmas in basketball to allow for more byes during the regular season.
