Wasn't Jones' injuries ACLs? He seems to have come back fine. I think it is all to do with the physio team, planning. support, facilities and so on. We seem to be well covered there, and they seem to be respected and supported by the players and management. I think Palmer will come back in as good shape as he can be.
I totally agree. I think we need at least 2 more CMs anyway, now Bostock and JoB have gone, to provide competition and allow rotation. I would be concerned starting the season with a midfield group of Crowley and Austin, and Robertson and Palmer covering attacking and defensive duties respectively.
