Ok, I'll help you out.
Amateurs off the field - The whole Robbie Farah saga has been childish on both sides and handled with the level of professionalism expected when a 6 year old oversees an argument between two 3 year olds over who gets the ice cream. Jason Taylor is an atrocious communicator to his players and the media. The front office has got to be one of the laziest recruitment and retention teams in the NRL.
On the field - Defence, pure and simple. The defensive failures of Naiqama and Moses are glaring and obvious to all, yet they still defend besides each other. Naiqama has enough size to make good impact, but far too often he will run up and in but not at a player. It's left his winger complete outnumbered and with our cover defence bugger all time to plug the hole in the defensive line. Every team has expolited it this year, some better than others.
The halves - The seem to be each others hinderance, instead of being a dynamic duo like the media keeps telling us they are. Both play exceptionally better when the other isn't playing. The criticism that Farah was cramping their style may have had some truth to it, but not much. The kicking game is unimaginative, there are no combinations. The link with Brooks and Tedesco is actually more about Brooks changing direction and then Tedesco doing 90% of the work thereafter.
Hooker - We had Cherrington ready to play first grade regularly this year and the club bought the injured Matt Ballin, in a patrhetic power play to force Farah to leave. What ensued is Ballin playing for about an hour of the season and injured for the rest, Cherrington getting disgruntled as the coach believed second rowers could become makeshift hookers and be better than him, so he left. If Farah leaves, the club will be left with the injury riddled Ballin and the talented Liddle, who has played about 15 minutes in the NRL and may have to step up to being an 80 minute player way way sooner than expected.
Bad signings/poor use of signings: The Tigers made a good signing in Michael Chee Kam and then refused to use him for most of the year, while Jordan Rankin who was barely a quality player in the poorer Superleague, walked into the starting side every week. Justin Hunt was immensely better but left to play out near the whole year in lower grades.
For a side whose coach was only focussing on improving the defence, he has achieved zero in that area.
