In comments at the SEC spring meetings in Destin, Florida, LSU AD Joe Alleva said it's an almost certainty LSU and Wisconsin will play in Houston's Reliant Stadium in 2014 with another date in iconic Lambeau Field sometime in the future after that in 2016, 2017, or 2018. Alleva said the contract is waiting to be signed.
This continues LSU's recent trend of playing neutral site games, such as the Cowboys Classic in Arlington, TX & the Chick-Fil-A Kick-Off game in Atlanta, GA. This also continues a recent national trend of playing these big out of conference neutral site games. It's an easy way for an athletic departmen to make $3-$4 million, which is more than they'd receive for a home game.
