I think Gibbsie was hard done-by.
His two penalties:
1. "Late hit" on McGuire: I think the shot was just a touch late. But the point of contact was the shoulder. At the same time, McGuire was sliding downwards in motion. Gibbsie pretty much put on a shoulder charge on the kicker, if a bit late. Penalisable but not severe. And defn not worth sending off for.
2. "High shot" on Ikin in the first half: VERY unlucky call. Gibbsie comes from the side and smothers Ikin who was attacking the line. Contact is with the arm across the left shoulder and forearm on the chest. A harsh call for mine.
In Gibbsie's defence, I'd like to have a bloke who can enforce a little. The Tigers do not have any players atm who dominate one-on-one tackles. Gibbsie, although a little clumsy, has good stopping power in defence.
Eg Morely makes many many more high tackles than Gibbsie, but the Roosters want him to enforce.
