Ideally, once Berry has fully developed, he takes over Laird's role (maybe not as much accumulation, but the same defensive/clearance impact and more impact per possession), and Laird moves back into defence in his final years ('25 or '26 onwards)you are right, the mix is critical.
We have Laird who is an out and out accumulator. We have Berry who is developing into a very tough contested player that loves to stick a tackle. We have Shoenberg who if he can improve on where he is at, is a class smooth moving young mid....then we have Pedlar. IF Pedlar can get over his injury worries, he has that x factor burst of speed from a contest and a long kick for goal. That is 4 different types in there. Then add in Rankine / Rachele in spurts with both having real x factor, Soligo as a classy user of the ball and we are building a quality young midfield (apart from Laird)
Pedlar definitely the wildcard - still very much unproven as a midfield prospect, but if he can get that part of his game going it'll be huge for us
