Both views are great. At 315, our seats lined up perfectly with the one goal line and you could easily see the entire perimeter of the field.
In 222, you saw 65 yards of the field perfectly. Plus, the scoreboard is on the far side of the field directly in front of you. I liked this section because you see what the QB sees. Being a student of all sports, I think I'd enjoy seeing plays develop and seeing how the QB see these developments.
Either way, you can't go wrong.
