Come on now, I never backed anyone in particular including O or Thompson but I can see why Sirmon would be considered a riskier hire. Thompson has been a position coach at an FBS school since 1999 and WAS DC at UCF for 3 years (04-06). O has been a HC and has been coaching DL at an FBS school since 1988. Sirmon was a GA as recently as 2010. Hard to compare the experience of Sirmon with either of the other 2 coaches. Now granted Sirmon's coaching career was more delayed by playing in the NFL for 7 years.
