Neither party is innocent. Lets look at the facts.
Radford might have held down too long, still didn't deserve the elbows to the head he recieved. This in-turn, did not warrant Radford's reaction to stand up and throw 3 punches which 2 connected while Bailey was lying on the floor unprotected
Bailey might have been given an easier ride if he had got up and let the handbags reach their natural conclusion but, as is usual with Bailey and why is he universally disliked (bar most Leeds fans) is that he went back in late to try and act the big, tough man and attempted to headbutt Long which luckily didn't connect.
Personally I think Bailey had this coming. He got away with his cowardly attack on Riley in the last second at Wembley as well as many years of dirty,niggly, third man in tactics.
In terms of the punishments dealt I think Radford was right to be sent off, you can't have players punching other players while they are on the ground unprotected, if at all. Nevertheless I think he should be given sending off sufficient because it happened in the heat of a fierce derby while being provoked by Bailey's elbows.
One things for sure, it will be VERY tasty if Leeds and Hull meet in the play-offs (if that is possible before the Grand Final)
