From Iowa's Black Shart-Soiled Pants fan page, or whatever it's called:
"Shannon’s name may sound familiar as he’s a name that’s been on the Hawkeye radar for some time as a top target on the defensive line. However, Shannon made an unofficial to Minnesota and PJ Fleck back in early May. As he’s known to do, Fleck put on the high pressure pitch and Shannon made his verbal commitment to Minnesota before leaving Minneapolis.
It seems as though those tactics were a bit of a short term gain, long term loss for the Golden Gophers as Shannon decommitted less than three weeks later on May 28th. At that time, he re-opened his commitment, but had a top two of Iowa and Minnesota. After not attending the Hawkeyes’ recent recruiting tailgater, the conventional wisdom was he may be leaning back to Minnesota. Today, he proved the conventional wisdom wrong."
Wether he puts on the pressure or not, I get some enjoyment from the thought of PJ Fleck irritating anyone from Iowa.
