Mention of Conroy having long(ish) term injury above, we have Kelly coming back (hopefully) from a long injury then we have a host of guys in the past with bad injuries who never really came back, Ronan Fallon springs to mind (he left the Dublin team with injury as one of the best centre backs in the country and his last involvement with Dublin after his return was as an unused sub in the defeat to Antrim). Also to my mind Treacy, although a very good hurler, seemed to lose a fair bit of speed and just general conditioning after his cruciate.
My point really is, is there an issue in Dublin with how injuries are handled with the hurlers. I am sure ye can all think of more examples then the above. With the footballers, practically everybody comes back to where they were before, even with cruciates, but I am not sure it is so with the hurlers.
