Successful FCS coach with good O and D
That successful record and performance at a lower, like FCS, level isn't always a good or accurate barometer.
The previous HC before the current coach at JMU, believe his name is "Houston", had a highly successful tenure in Harrisonburg, including, IIRC, a FCS National Championship. He is now at East Carolina, in 3rd or perhaps 4th season, and the Pirates are currently something like 1-7 and pretty much in the basement of the AAC!
