You see it a good bit when interims take over, the team usually responds by playing with a bit of fire. I still think this is a product of playing the Falcons at the right time, and a series of bad teams on the schedule.
I like Rizz, but we need a new GM and that GM needs to bring in his guy. Interims who get the post HC firing bump and end up with the permanent job, usually dont work out. The Raiders did it with Antonio Pierce, and that certainly isnt working out.
In the last 15 years, there have been 4 interim coaches that have had the interim tag removed. They are a combined 44-78.
