Guess who?

Can you name who's in this photo? Bonus points to those that can correctly guess who's on the poster!

I'm issuing an all points bulletin. I seem to be missing my coveted Nebraska sweatshirt. I cannot remember the last time I wore it, but with the current Cleveland temps I'm longing for it. Does anyone remember seeing me it? Did I loan it to you? Is it in your car? Your closet? HELP!!!
