Yes, Dabo was on thin ice, but it is easier to get off of the hot seat when your team is at least decent. That's how Gus has spent his entire career off/on the hot seat - he feels pressure, and his team actually is good enough to pull off an upset. Dabo would have been s**t-canned if he followed up his 6-7 2010 season with another 6-6 the next year.
Pruitt's teams are so terrible that I'm not sure it's possible. I mean, he will get off the hot seat if he starts winning, but it is just so unlikely.
