I'm not defending Gilbride but those Oiler teams were very successful and it was large part due to their offensive passing attack.
Also, many coaches are not liked, but most importantly are they respected?
"They come to the line of scrimmage and the first thing they do is start looking for me....I know, and they know. When they’d find me they’d start screaming: 56 left ! 56 left!....So there’s this thing I did. After the play was over I’d come up behind them and whisper: don’t worry where I am. I’ll tell you when I get there."

The one thing I got from the football life take on the punch is that Killdrive was good and ready to punch back if he wasn't restrained by a player. And it seems like he takes great joy in destroying Buddy's progeny too... he lost to Buddy (who took the HC job of the Cardinals) in 1994 while Killdrive stayed on the sinking Oilers ship, but after that, Killdrive as OC or HC has gone 7-3 against the brothers Ryan at DC or HC...
-As OC of PIT, Split with BAL (Rex DC) twice in 1999 and 2000 (2-2)
-As OC of NYG, beat BAL in 2008 (Rex DC), beat NYJ in 2011 (Rex HC), and went 3-1 against Dallas in Rob's tenure as DC (total of 5-1)
Side note, he DID go 1-3 vs the Patriots in 2002-03 while Rob was the linebackers coach and he was Buffalo's HC, in addition to losing in Baltimore (Rex) and winning vs Oakland (Rob) while he was QB coach for the giants. But safe to say it was not his offense vs the Ryan defense in either scenario.
