Every time this topic has come up in the past decade or so, everyone seems to believe the loss of games in Texas, where Nebraska had recruited well in its glory days in the Big 8, really hurt it in the move to the Big Ten. Nebraska then had a tougher time pulling recruits in Texas and were recruiting more in Chicago and other areas in the upper Midwest against better-situated programs that had long-established reputations in the region.
I'm not suggesting that UW will face a similar fate (it isn't in the same recruiting situation as Nebraska was for various reasons, and still will be playing in SoCal in-conference), but curious as to your take on that.
