I'm going to assume you understand the difference between should/ought and must.
I pay to post on this board and have complied, I think, to the posting rules. That's what gives me the right to tell others my opinion of their posts. That is kind of how these sites work. We all are sharing opinions. For example who are you to criticize or even understand Brian or Kirk Ferentz. Do you know more about football, pretty sure no. Do you see the guys practice, pretty sure no. Yet you have no problem saying what the Ferentz's should do, or what should be done to them. It's how the 1st Amendment works, at least for now.
I chose to share my opinion about your quote because the smarmy gloating over Iowa bad news has become a tedious monotony of actual animosity from people that purport to be Iowa fans. Frankly, hoping to point you in a healthier direction since you very clearly do not appreciate Iowa football and derive satisfaction if not pleasure from bad news. That's a nasty negative way to live. I think you sound more like an Ohio State or Michigan fan. They almost always win, score tons of points. What's not there for you to love? You should thank me.
