So do you reckon playing him right now is doing him any good? If I was WC I would be more pragmatic, have the attitude that you will only play fit players and forget Judd for the rest of the year. In all likelihood, without Kerr and Cousins you are not going to win the flag, so give Judd the surgery or rest he so badly requires.
Yep he is treading water atm, not going to recover this season, cut your losses and leave him out for the rest of the year, which is likely to be one more game anyway.
