You don't really have to rate big in any of those stats to be a good hooker... it's misleading trying to claim he's not performing because of that.
I agree with you, he's shit... but it's his service from dummy half that still leaves so much to be desired. Our halves don't get quality ball when Gids is out there... there is often indecision or confusion from those around him. I feel like the worst thing Gids brings to the team is his lack of mental fortitude. I look at him as the absolute archetype of us losing our bundle when something goes wrong. He far too often walks the victim route, rather than trying to be the bigger man and getting on with things. This has been the case for many, many years... and it definitely has an effect on the rest of the team.
In even simpler terms, the guy just isn't a winner anymore... and only ever was for a brief couple of years in the middle of his career.
