I've got tickets on Row 65. I've asked around, and found out the following:
You should be able to see the entire field, unless you are right behind a pillar (Row 52, I believe), and then you might have 10% obstruction, which can be avoided by leaning forward, back, etc.
You may have to lean to get a view of the video screen/scoreboard, but I believe there are miniature scoreboards up under the overhang w/ time, score, down and distance.
If it's raining, drizzling, or sleeting, you'll be very thankful. If it's cold and sunny, you'll be wishing you weren't under the overhang. Dress warmly either way, because it can be cold and windy underneath there.
