Mcgovern is a much better mark than darling but im not sure ive ever seen him lay a tackle.Vardy rarely chases or tackles.We have to be wary of filling up with players who dont work hard.Actually I have seen Darling lay some good tackles - perhaps not lately though but he is capable of it. It's just that the team as a whole now play this stupid corralling type game they obviously have been instructed to play!
