Marking is a talent. It's in the hands. The Weid has modest talent and is unlikely to improve to any significant level. Naughton showed how much better he is. If he gets the hands on it, it sticks even under pressure. Those who talk about grabbing the second grab, know little about being a good mark. Good marks don't needed a second grab. There are a range of players of all sizes in our team who are great competative marks, May Lever Salem, Rivers, possibly Petty, Brayshaw, Petracca, Oliver, Viney, Fritzsche, Gawn Tom Mac. They will mark in a competative situation, against comparatively similar size. I would not trust the following to consistently win a marking competition, Hibberd, Hunt, Spargo, Neil Bullen. Some players are ok Langdon, Harmes. Not sure about Jordon yet.
Talented marks display it from early days eg Rivers. Weid has been in the system some 7 years and he still is little more than modest. Yes experience and confidence will help, but he'll never be great. It's a talent some have and some don't (Unfortunately Jack Watts did't have it) just like kicking for goal. Jack Watts did have the kicking talent, Max Gawn doesn't but Tom Mac does. The Weid has a beautiful kicking style, but beyond 30 metres he is merely a 50 50 chance. He's got an awful lot of work to do to meet our hopes.
