Actually he seems like a very decent fellow; unfortunately he's just an awful coach.
I live near P'burgh and watched this guy's entire career firsthand; he was entertaining at first but it didn't take long to realize that he had no business being an NFL head coach.
By the time he finally got out of there, after soooooo many years of utterly mangling hyper-talented teams, Stillers fans we're thrilled to see him go; and I don't know a single one of them who wants anything to do with the guy ever again. If you had actually watched him embarrass himself week in and week out, I'd bet my house you wouldn't want him anywhere near the Bills organization in any capacity whatsoever.
