It would definitely be an unexpected call seeing him at the start of the season and something I dont think will happen. But I don't think end of season VFL form was as poor as it has been presented at times. He got a lot better throughout the season and started to take the game on more rather than looking lost. He's put a good amount of size on now so is something you would want pushing for selection in the 2nd half of the season.
I'm not as big on Battle being a defender as most others. I think he is a defensive downgrade on the Howard, Wilkie, Highmore trio while also not adding any extra height to that combination. He'd be a back-up option for me.
I remember going to watch the intraclub which must have been preseason 2018 or 2019. Marshall was just breaking out and out of nowhere looked like the best big man on the ground but second best was Battle as a KPB playing reasonably high up. He looked like a Wakelin and came out to meet balls that were loose and close checking his man which he did well. Can't remember who he played on but he was actually looking like a really high potential KPB. His best year was as a KPB which was probably before we grabbed Dougal. We do have quality double ups in a lot of positions that will hold players out of spots, there are some good players that will be out of the side that's for sure.
