And in all honesty - I don't have a problem with Sitake deciding that BYU needs a new defensive coordinator and moving Tuiaki into a different position or even letting him go.
I'm mostly speaking to the comparison to Bronco. People may not like Tuiaki's defense and may not think he's doing a great job - and I can see why. But I would not be a fan of "pulling a Bronco" - because the circumstances are different. Tuiaki is doing his best and has yet to pull a Jamie Hill.
If anything - Sitake needs to pull a Sitake - like he did with a prior offensive coordinator. But not a Bronco.
