His back wasn't turned, the pictures show him holding his hands up expecting a punch when Lees arm is at the bottom of the swing.
He turns to avoid being hit.
Apparently a poster on the forum who speaks to the players says Briers wasn't upset by the tackle but Ablett says something about Lees family, now to get such a response out of him like that I might assume it was his brother, put it this way what he said was so bang out of order when Lee went back to his players and told them it fired the whole team up to belt the living chuff out of Ablett.
Not excusing it, Lee should have been off be it Yellow or Red and I agree Childs was weak but as for the RFL ruling it is, like it or not the correct one. It's a grade A, Cummins called that right at the time and he should know better than anyone, Lee has no previous so with an EGP it is the correct decision to just get a fine and not a ban, no conspiracy, just simple black and white.
