Agree totally - Anyone who roars at a kid (actually, at anyone of any age), ‘two hands on the hurl’ or ‘on the ground’ or ‘drive it’ or starts to train kids to go for a high ball by trying to knock it down to the other hand or plays games where guys aren’t allowed pick the ball up needs to go to an actual game of hurling and point out a) how many balls are picked up by a two handed pick up, b)how many balls are hit on the ground and c) how many times they see ball knocked down to the waiting hand. I would estimate in the course of an average championship games the answers would be a)none, b)one and c) absolutely none. So in effect guys are spending 30% of their skills training doing stuff and being told stuff that will never, ever be used in a game situation.
You cannot pick the ball up at full sprint with two hands unless you are a contortionist. I suspect the majority of balls driven on the ground result in almost directly a score against and the knock down thing is just nonsense. As for playing training games where you can’t pick the ball up, what is the point. The game where you hit the ball on the ground using a stick is hockey, our game is hurling.
