Tossing up between either Loko and Humble out for Tedesco and Sironen or G.Burgess and Reece Robinson out for Tedesco and Farah. I'm guessing Tedesco will get the FB gig though.
Loko (Parra) has good byes so will be invaluable for fielding a squad during this period.
Humble must go but Sironen is a poor short term play, for not much more you can grab Campese who has been a 250-300K player in Supercoach previously and will play the whole season if required.
Robinson leaving would free up heaps of cash, and looking at his BE's coming up of 83 and 62 (if he scores 50 and then 60), he will lose 25K value. Getting Tedesco in makes a lot of sense to provide you some financial flexibility to make further changes as outlined below.
You have Nathan Smith who is a guy who just doesn't rate, I would be looking to get rid of him as soon as possible.
Farah is a short term play as mentioned previously as he will be playing origin, and tends to score 40-50 points when backing up (if he does at all), best to aim to get him after Origin. Sam Burgess will be invaluable during this period.
Mcillwrick is one that although he has a low BE of 12, his scores have also been poor (around 30 a match)which means that he won't go up my much (Lets say 5-10K at most).
Hold onto Toutai throughout origin as per my Loko comments.
Drury Low is another who you may want to get rid of, wait for the next debutant to play 2 games (and have potential to get a decent price rise) and then strike by replacing him.
Horo you should be aiming to lose after the origin season has finished, an inconsistent scoring player, hopefully he gains some value during the origin period by playing increased minutes.
