I was at the Kent State game when they did, but ok. But here you go.

"ESPECIALLY kickers. I was so ****** when Netten missed that first kick vs. KU. Partly because he missed the kick, but mostly because when he came to the sidelines (I'm in row 10 right in front of the kickers' warmup area), the entire crowd was ******** at him and booing him. Shut the **** up, people. He's a kicker. He's already in his own head making things worse. He doesn't need sections 30 and 31 in there too. That's not helping."

"I expect my team to put effort into the game. I also agree with negativity towards the boo-birds when I hear booing at bad plays (meaning where a player tried and screwed up) or when a player got injured."
"This exactly. At the end of the first half people were booing, I told my brother next to me that this is more embarrassing than us being down 28 at half. You are not helping when you boo our own team, if anything you are discouraging the team. In addition you make our fanbase look like ******. Leave the booing to eastern Iowa. We are classier than that at ISU."
"If players or coaches don't want to get booed they should play and coach better."
"Neither did I, but there were a few around us that did...and I'm with Sparkplug on this one.
Class-less move to boo your team (coaches, play calling, or players). I'd prefer that Cyclone fans not be "that guy"."

"The Students who boo need to show some maturity and grow up. I don't like or condone the BOOING of athletes."

"Just for the record, there were some booers at the last hgame. I was surprised. It was still a close game. I do not think booing our team is productive at all."

"Got in a bit of a confrontation with a kid sitting behind me in the student section. Other than the fact that he was a giant D-bag, he had 0 knowledge of the game and any time Jantz would throw an incomplete pass would yell "BARNETTTTT!" Now I know Steele had a horrible game, but this was within the first 5 minutes of the game. Along with this, he was constantly booing his own team and even yelled "Get off the field you ******* panzy" when (I think it was) Tuftee was down on the ground and needed help to get to the sideline. Anyway, I turned around and gave him a piece of my mind, complete with real analysis of what was going on in the game and why he sounded like an idiot and he and his friends hit the road."
Lol this is your evidence? Of course some idiots boo certain situations. Iowa State is a great fan base. They'd never boo their own team off the field
