Erickson took over an Oregon State team in 1999 that not only had not had a winning season in 29 seasons, they had won TWO OR FEWER games 17 of those 29 years. Another five of those they'd won three, meaning that in 22 of the 29 seasons preceding Erickson's arrival, Oregon State had gone 3-8 or worse.
In his first year, they went to their first bowl game since the 1964 Rose Bowl and for only the fifth time ever with a 7-5 record. The next year, they went 11-1 and lost only to Washington and gave them a better game than "we wuz robbed" Miami did. Granted, he couldn't keep it at 11-1, but do you really think Dabo could go 11-1 at OREGON STATE?
And keep in mind he didn't get fired, he got called by the NFL.
Again, I think Dabo is the better college coach, but the "he inherited Miami" doesn't fly with what Erickson had to do at Corvallis. And for what it's worth, he put that program on a solid foundation for years as they had winning seasons in 6 of the 7 years after Erickson left.
