Basically, the better recruits. Oklahoma doesn't produce more than a couple of D-1 prospects of quality per year. You need other sources. What is the reason that these recruits will be attracted to you?
OU because of its state population and the competitive athletes concentration in competitor's regions has always had difficulties recruiting in
all sports relative to its peer schools i.e. Texas, A&M, Ohio State, LSU, Alabama, Georgia, FSU, USC in football, Alabama, Florida, FSU, Oregon, UCLA, Cal, LSU and Washington in softball and Florida, UCLA, LSU, Alabama and Georgia in women's gymnastics and Stanford, Illinois, Minnesota, Michigan, Ohio State and Penn State in men's gymnastics, etc.
If you look at historical national performance in all the sports it is a concentration of a few schools that continually dominate the final standing, the super six, the WCWS, CWS and Final Fours/Elite Eights. Once in that top eschelon given there is coaching, money, history and facilities most programs are capable of sustaining that traditional success.
Sherri did so for a decade dominating the Big 12, Baylor and Texas ending in 2010. OU's still has the history, the money and the facilities to compete for the very best players but that talent has been missing for nearly another decade. Unfortunately Sherri has let the program slide and instead of competing for championships she is fighting to make the tournament as a lower seed. That is a progessive transition in the wrong direction. OU is fully capable of attracting talent on a national basis that will allow them to compete annually for the Big 12 conference championships. Asking OU to again be a national power is asking to much. But any argument that you cannot adequate talent to come to Norman to win the Big 12 is poppycock.
Chris Beard under more difficult circumstances than Sherri has was hired as the basketball coach at Texas Tech for the 2016 season and he has recruited and developed talent to the point that he has a top ten team that has beaten Kansas in the Phog and will push the hawks for the conference title this year. Amazing what you can do with attitude and effort.
Mark Williams, KJ Kindler, Patty Gasso, Bob Stoops, Lincoln Riley, John Roddick are Ryan Hybil are or were (Stoops & Roddick) able to successfully recruit top talent to Norman. They all did so with the same location disadvantages Sherri has except for the reputation they have created and maintained for themselves along with working their tails off for their talent.
Expecting Sherri's teams to compete at the same level of the football, softball, men's tennis, men's golf, the gymnastics teams or maybe any of the 9 sports that have won a conference championship since Sherri last won one may be asking too much. But to think that she could be a serious contender annually for conference honors and win 35-45% of her games against her chief conference rivals is not asking too much.
If the Sooners are still floundering like they are now in the 2021 season it is time for Sherri to be gone. She will have had 11 seasons to have made her team something more than barely qualifying for the tournament. She set the standard. She needs to live up to it. She is definitely compensated to do such.
