At the time, Salem looked good as he had a winning record, played a more wide open style at N. Arizona, and was a back-up QB on the last national championship team in '60 (tossing a key pass that broke open the big game that year, with Iowa, which was no. 1, the Gophers no. 2 in one poll, 3 in the other). It wasn't until he ran out of Stoll's players that it became apparent he couldn't recruit. But you are right, Hayden did for Iowa what Alvarez did later for Wisconsin. The U made many bad coaching hires, as we know now.
