That is correct. Erickson coached in Washington at Washington State, Idaho at University of Idaho and Oregon at Oregon State. As far as the Pac-10, the aforementioned as well as California at Fresno State and San Jose State (obviously not Pac-10 schools, but Cali schools, so they count!), and Arizona at Arizona State. Adding in the Pac-12, he added Utah at the University of Utah. As far as the different levels (High school, FCS, FBS, NFL) he included Billings Central Catholic HS in Montana, Montana State (FCS), the aforementioned Pac-10 schools and a few others (FBS) and stints with the Seahawks and 49ers.
I kind of had a hunch SunDevilCollection would be the one to get this, seeing as his time at Arizona State were some of his most successful years, winning a Pac-10 league Championship, and being named (Pac-10) Coach of the Year.
