Polo just had an opinion that ran counter to most - and because of it many had a problem with him, and therefor he became the problem...so ultimately the problem wasn't Polo as you allude to above, but his opinion.
No. Just... No.
He was always right, and anyone who disagreed was an idiot/fool/whatever, and a [insert cliche about bo lovers/kooliad/etc]. Like Bo, he got some things right. But he did it without class and was many times a bully to people. Many times, he'd come in and make it about him and his opinion, even in a completely unrelated topic. He was a master of veiled insults and skirted the rules for a long time. He obviously had some issues with the admins & mods, hence him getting the boot.
Bascially, Polo was the Bo Pelini of Huskerboard.
