Whilst I'm all for the odious John Terry being banned for as long as possible, you have to remember that he has been acquitted in the Magistrates' Court, therefore, it's highly questionable whether the FA should have proceeded at all.
The difference between the Suarez case and Terry would appear to be that Suarez tried his best to deny the offence, and his defence was not accepted; Terry doesn't deny using the words but said that he used them to deny actually calling Anton Ferdi a fuckin' black ****. In so doing, he admitted using those words on the pitch, and thereby he is guilty of the offence. But, if the FA basically accepted that he wasn't using the words in the insulting way for which he was originally charged, they will have accepted that there was some mitigation so as to distinguish this case from the Suarez case.
Shorter ban, bigger fine than Suarez but, as we all know, money is no object.
To me, they've fudged the issue; if the mitigation was strong, he shouldn't have been charged in the first place - especially after going through the full legal process in the Magistrates' Court. If the mitigation wasn't accepted, he should have got the same ban as Suarez, at least.
I suspect he will just leave well alone now and serve the ban.
