Who has been Mullen's best defensive coordinator, and where will Sirmon rank?
Before the media found out Sirmon was who Mullen hired as the next defensive coordinator, I had no idea who Mullen would hire. Despite that, I probably had more of an idea than FootballScoop. Sirmon could be a good or bad coordinator, and it wouldn't be surprising. After thinking about Sirmon's hire, I asked myself where his hiring ranked among the rest of Mullen's defensive coordinator hires.
Mullen has hired Carl Torbush (2009), Manny Diaz (2010), Chris Wilson (2011-2012), Geoff Collins (2013-2014), Manny Diaz again (2015), and as previously mentioned, Sirmon for 2016.
