If the NRL are fair dinkum, neither have a case to answer.
Klemmer was a case of a taller player (him) hitting a shorter player (Storm) and his bicep hitting his head was only avoidable if Klemmer bends over. Also, a Storm player did an almost identical tackle later that nothing was said about.
Morris went up for the ball, grabbed Waqa's arm and came down with it and held on. Nothing in it. A chicken wing is when the defender has the player on the ground and wrenches his arm. Morris had his arm (the only part of his body he could grab) from the time they went up for the ball to when the tackle was complete.
I doubt Morris would have been reported if Slater wasn't just before for the knee in the back.
Another thing that really shits me is the commentators whinging about the video ref intervening. They should be whinging to their directors ffs! If it wasn't for their super slo mo of only the latter part of Morris's tackle, it wouldn't have looked bad.
