I've been to Everbank many times since it was called Alltech, and enjoyed it every single game win or lose. It doesn't have all of the fancy aspects of an NFL stadium like the Dallas Cowboys or Houston Texans have, but it's a beautiful stadium. The new upgrades for the upcoming season will make it even better for fans.
The last game we attended was while the Texans were in town last September. It was the Jags first home game of the 2012 season so everyone was in high spirits but they ended up losing by three touchdowns so the upper deck emptied out a good bit with 5 minutes left in the game.
We were in row G of 433 so we had great seats although I think every fan has the preference of sitting closer. The view is good from all seats in the 400s regardless. Since the corners are blocked off with covered tarps, every seat is very "central". I wish they would widen the seats a little more and give fans a little more leg space but they want you to pay for those amenities via the Touchdown Club.
