Patterson seems a huge upgrade on Parkhouse at the very least. Singh, Cacace and Fox seem ready to compete for first team spots regularly. Ridenton's had a decent break-out season, although I wonder if we need an upgrade on him (don't ask me for names) if we want to make the top six (or higher) next season. Haven't seen enough of Rogerson, don't think what I've seen is enough to justify a regular spot on the bench for next season.
I would honestly keep Kaludjerovic. Kalu just ended a goal-drought sure, but we don't want to go back to the days of #notastriker. Unless the club has a replacement lined up that they're confident is better, or at least matches Kalu, keep him on. It seems like Rossi is on his way out, meh. Wouldn't mind if we kept Ljucic on, not sure what I think of Paracki for next season.
