The injuries and slow decline in Clark's form has been sad to see as he is one of the most consistent performers we have had and is probably underrated in the context of all time Wire players. He has given us the best part of a decade as a genuine top SL player. I do think that like with Chris Hill, staying with us during his prime years has meant he's missed out a bit when he could have gone to the NRL and been a real megastar.
If he goes to Saints he could have some late career success and pick up the SL ring that he deserved with us, so good luck to him. I could even find myself rooting for Saints in a Grand Final if Clark was there.
