Former Hawkeyes buzzing after Iowa moves to 7-0

As you might expect, Iowa football alumni are quite proud of their former team these days.

The 17th-ranked Hawkeyes improved to 7-0 overall and 3-0 in the Big Ten with a punishing 40-10 win at No. 21 Northwestern on Saturday.

Current players are not permitted to use Twitter, but former players have plenty to share.

Here's a sampling, including a rousing rendition of Iowa's fight song from Colin Cole:

The noise is certainly more positive now than it was before the season, and Mitch King and Adam Gettis want to remind folks of that:
