Very good player, he has a decent long kicking game, great positive mindset, good speed and vision. Although he doesn't put his teammates into space, that has at least as much to do with the line runners as it does with himself.
The Warriors long had a tradition of forwards setting up runners with offloads, a lot more than the halves passing to hole runners in tight lines, which requires a lot more sophistication on the part of the runner. This is one aspect where our current team severely lack, apart from Locke.
Back on Maloney, his defense gets a bit of stick, but every game I see he makes several last ditch efforts when he chases guys from out of nowhere and only just reaches them, as a result unable to complete the tackle. He has very good vision in defense and is definitely willing. It probably helps to have a couple of tackling machines around him in Luck and now Taylor.
