I've heard of Billy Sims. Certainly OU has recruited Texas prior to Stoops, and has gotten some good players. And if college FB rosters were made up of 1 player, you might have point. But they aren't. Winning college FB rosters are 3-4 deep of good players.
Lets look at the makeup of the OU rosters prior to Stoops:
(stats from
SoonerStats.com - Oklahoma Sooners Football, Basketball, and Baseball Scores, Records, and Stats)
year--players from OK or TX--coach--OK players/TX players
1998--OK 64, TX 31--Blake--2.06
1997--OK 63, TX 31--Blake--2.03
1996--OK 56, TX 35--Blake--1.60
1995--OK 50, TX 43--Schnell--1.16
1994--TX 53, OK 40--Gibbs--0.75
1993--TX 42, OK 37--Gibbs--0.88
1992--TX 49, OK 35--Gibbs--0.71
1991--TX 55, OK 35--Gibbs--0.64
1990--TX 45, OK 40--Gibbs--0.89
1989--OK 42, TX 39--Gibbs--1.08
1988--OK 46, TX 44--Switzer--1.05
1987--OK 43, TX 37--Switzer--1.16
1986--OK 50, TX 29--Switzer--1.72
1985--OK 49, TX 29--Switzer--1.69
1984--OK 51, TX 34--Switzer--1.50
1983--OK 49, TX 31--Switzer--1.58
1982--OK 44, TX 32--Switzer--1.38
1981--OK 51, TX 33--Switzer--1.55
1980--OK 60, TX 34--Switzer--1.76
1979--OK 68, TX 37--Switzer--1.84
Prior to Stoops, and spanning back 30 years, Gibbs was the only coach who had more TX players than OU players, and Gibbs was not particulalry successful by OU standards (Walden beat him in Norman). Other than Gibbs, the last two years of Switzer, and the HS year, the OU roster was heavily comprised of OK players relative to TX players.
Now, let look at the last 6 years of Stoops
year--players from OK or TX--coach--OK players/TX players
2010--TX 57, OK 29--Stoops--0.50
2009--TX 45, OK 33--Stoops--0.73
2008--TX 38, OK 33--Stoops--0.86
2007--TX 44, OK 29--Stoops--0.65
2006--TX 50, OK 30--Stoops--0.60
2005--TX 48, OK 30--Stoops--0.62
Stoops is recruiting TX more heavily than his recent predecessors, and his rosters are dominated with TX players moreso than any OU rosters in recent history. And Stoops is winning, which means he is getting good Texas players, and not scraps left over from UT and A&M. Obviously, Stoops has seen something that is causing him to stack his roster with TX players relative to OK players. Apparently he believes he needs a roster dominated by TX players to be successful. If Stoops wanted to, I'm sure, he could stack his roster with OK players just like Blake did.
The bottom line is that as far as the Big 12 goes, OU FB
wasn't winning until Stoops came in and started heavily recruiting TX, and landing good TX players. Baring a miracle of Biblical proportions, OU is going where UT goes, or somewhere where Stoops' heavy TX ties will not be disrupted. If you are one of those who thinks that OU is going to dump UT for ISU,KU,KSU,CO,and NU to resurrect the old Big 8, you best start praying now for that Biblical miracle.
