Think we need to give him an extended run at it now, he's got all the tools - just needs refinement and experience to ensure that he's utilising the tools to the best of ability. With his height, physique and leap - every mark should effectively be uncontested - aka, get to the fall of the ball, outmuscle them (given you're a very strong man), leap (higher than anyone else can) and pick the mark. That's obviously an oversimplification - but the nice this is that he's getting to the contests, now he just needs to capitalise.
The best thing is - that he never needs to be the "number one tall" - I feel fairly comfortable in saying that Browny and Mason are our two key 190+ cm forwards going forawrd- but be being so tall and athletic, means that Maj ultimately takes away a key defender - and a tall key defender, which makes life for Browny so much easier. The experience of playing with Drewy shouldn't be undervalued as well. Learn how forwards operate when they "don't" have the ball, where to go, how to chase to ensure that even if you're not having goals, you're having an impactful game.
A number of times last night (particularly when playing in the middle) Grundy just got away from him, but this comes with game time.
