This is the recruiting myth about Nebraska. Nebraska was in the Big 8 until 1996 and the Big 8 had no presence in Texas as it was made up of: Nebraska, Oklahoma, Oklahoma St., Kansas, Kansas St., Missouri, Colorado, Iowa St. I looked at Nebraska's roster from 1994 when they were in the Big 8, went 13-0, beat Miami in the Orange Bowl, and ended up ranked #1. By far, most of the players were from Nebraska, but the other states most represented on the roster:
California 12
New Jersey 6
Texas 6
Florida 5
And, in general, few of the top players in Nebraska history are from Texas except Turner Gill.
