Mullen effectively sealed his fate after losing to Georgia he talked about how recruiting wasn't a 24/7/365 job at the same time Kirby Smart, who just kicked his ass owning the #1 team in the country, stated that recruiting was a full time job for his staff and by far their most important job.
Washington needs a HC that is absolutely relentless and won't be a beta to Oregon ... that's not Dan Mullen.
Mullen was great at Mississippi State ... that's the ideal job for him given his personality in that you're really happy with a Top 15-25 team.
I'd be surprised if he's out of work for that long, there are some open jobs that I would be lining up to talk to Mullen on ... just not UW.
