Is that fans and players could have confidence that Bronco could right the ship defensively with a quick turnaround - and he largely did. Why should anyone have that same level of confidence in Kalani, given his track record? Hiring a replacement DC at this point in the year is a non-starter, so the HC taking over defensive duties is the only alternative, and I wouldn't see that going any better for Kalani than it's gone for Tuiaki.
