Yes. The SEC is expected to mandate a conference wide clear-bag policy for the 2017 season. Across the SEC, Auburn, Florida, Mississippi State, Tennessee, Texas A&M, South Carolina and LSU will institute clear bag policies for the 2016 season. Nationally, Michigan, Ohio State, Penn State and Michigan State do not allow spectators to carry any bags into their stadiums.
Now if you were to look up the current bag policy on the Mississippi State Athletics website, there currently is not a bag policy in place for the 2016 season. However, if you go to the Fanguide for the 2015 Football season, you will find this printed.
