My 2 pennys worth,
Imo it dosent matter what the extent of the injury is, the punishment and decision should rest on the actions.
This was an unprovoked attack, a cowardly act for which he should be banned. He wasnt trying to get off the floor he punched stosic intentionally in the face, and how the RFL can say there was accidental contact with the eye, shouldnt really matter where in the face cunningham (or burger king) hit stosic, it should still represent a ban.
How he gets off scotch free, god knows. Im not angry that a saints players been let off its the consitency issue that concerns me, as i can almost guarantee latu wouldnt have got away with it. Although he can now hopefully beat, wigan, quins and huddersfield in the coming weeks, we'd all like to see that
