Why do you equate “helping out our other midfielders” with getting clearances? It depends on who it is, of course, but with Serong and Brayshaw, I see the contribution of the big body of Fyfe (e.g.) to be mostly blocking/protecting the loose ball or the space for Serong to swoop, or alternatively getting a hand in or giving a good shove to disrupt oppo gets and passes. Johnno doesn’t do quite the same (because he can’t), but he looks to me to play the defensive role mostly and will accordingly be a fraction late to the loose ball when it’s “his turn”. Ideally, yes, he will get quicker both at reading and reacting, but he’s still relatively new to the inside stoppage set up and could do with a little more time to develop his craft at AFL level.That thought has crossed my mind and it's a little concerning. Yes I know we should expect the coaches to know better but I still think we are missing that big bodied midfielder (190+ cm) to help out our other midfielders and that's why I pegged Johnson or Jackson to fill that role. There aren't many 193cm midfielders in the game so I just can't help but feel we aren't getting the most out of Johno by playing him outside the contest.
Meanwhile, Serong is no doubt great at getting clearances, but he doesn’t get heaps of clearances simply because he’s great at getting them. We set up to maximise his chances of getting them.
