You have every right to protest but I would stop short of personal abuse (some Sunderland fans went too far). It makes me sick when fellow managers come out in support of a struggling manager, the only thing they are thinking is "lets keep crap managers in a job then we're more likely to get 3 points when we play them". Moyes, Fergussson, Rednapp etc are just 2 faced. If I'm honest I'd like Kean to stay in a job then there will be at least 1 team below us at the end of the season. What annoyed me about Steve Bruce was he was obviously completely out of his depth, bought utter rubbish then kept making excuses but throughout he kept picking up his £80,000 a week, disgraceful. The rest of us are doing a good job for a few hundred quid a week when he was doing an unbelievably bad job and getting £80,000 per week. Blackburn fans you keep protesting and I hope you get what you want.
Very strong article supporting your protests here on Salut Sunderland. http://salutsunderland.com/2011/12/birflatt-boy-go-steve-go-but-he-means-blackburn-this-time/
