They were 1 dodgy decision away from a qualifying finals spot last year, and this year they struggle on the back of Bowen aging getting on, Tamou being distracted, no decent hooker and the continue fight to find JT a halves partner.
Look at the players who have improved under Henry - Tamou became one of the best props in the league, emergence of T.Sims, improvements of Linnett, Graham, etc.
Henry has a winning % of just under 50% from Canberra and North QLD (teams that 'traditionally' struggle away from home due to climate changes, long trips, etc) in 6 years of coaching. He may not be the best in the business, but he is an improvement on Price and much better than Sheens IMO. With the squad we are looking at next year, he should be able to do quite well.
