Dylan is hard at the ball.
Just needs to bulk up so he doesn't get brushed aside.
I've seen him play aswell TG, he's not the hardest player going around, nor is he soft. It's more his body shape that's keeping him from being a physically minded player.
Simpson is still a skinny sort, but he is tough as nails and this is what Buckley will become IMO. He will never be a physically imposing player but he will be hard at the ball once he adds some size.
So in essence, I agree with you.
