Rehashing the hiring of Stallings is pointless; it happened.
And for those that want to dump Stallings, firing a coach is always easy, and often a popular sentiment. But, finding a good replacement isn't usually as easy. Tennessee football gets a new HC ever 2-3 years these days, and they quickly canned Jones this year. They've been turned down by a half a dozen coaches already, and they're still searching. Its getting embarrassing.
Like him or not, firing Stallings early will just make the Pitt job less attractive.
