Dave, you were a bit pre-emptory but apology not needed, blame it on the threading.
There's probably more we agree with here than disagree. At the end of it all the ban is rather arbitrary. I think a case can be made for anything from three to ten matches.
I'm not surprised the FA didn't give top priority to Suarez's list of "similar" cases. I have a little feeling they didn't include his previous biting incident!
The "kicking the ball boy" incident was certainly extraordinary in the sense of being unusual. However they may have decided that Hazzard had no bad intent and didn't in fact kick the ball boy and so do not see that as extraordinary in the sense of needing extraordinary punishment. I think the shoving and tripping of referees to be interesting parallels. They plainly don't rate as violent and yet we see bans of ten or eleven matches. So there is a class of disparate actions which are seen as meriting extraordinary punishment even though no-one is physically hurt. We have touching the ref, biting now, and increasingly, racial abuse.
When you appeal for a similar case to compare it to the elephant in the room is the previous Suarez biting incident. No matter what they say, I don't believe that that incident pand the subsequent ban, and Suarez's more recent bans and warnings, didn't enter their heads or influence the decision. You might say it shouldn't have. I think everyone outside Liverpool thinks it should.
Gotta go now - just drank a glass of beetroot juice and I think I'm going to throw up.
