Course not.
However, whilst the buck stops with Sinfield, I don't think anyone can entirely blame him for the mess we've been in. GH is the one constant over the past few years and the deterioration in the squad is clearly down to him in the main.
Sinfield messed up a few early decisions, but even then I can sort of understand his logic re Ablett and JJB - he wanted to keep some of the Golden Generation culture around. Clearly hasn't paid off and is a waste of cap space and I didn't agree with it, but it makes a certain amount of sense. Furner was clearly a big mistake, again in retrospect. But he wasn't a tyro (as some kept repeating) - he coached Raiders first grade for several years and was an experienced assistant in the NRL. I thought he'd go OK, but it didn't work out.
Beyond the above I'm not sure what else you could blame Sinfield for? Crosby presumably passed a medical before signing, most of the others until this week have been squad players. Even then they were signed under Furner, particularly Merrin who he seemed desperate to get. Sinfield could possibly be asked to explain why w have spent marquee money on positions that aren't vital to success, but he was also hamstrung by Lolohea having been signed to play 6 and a roster full of sub-par players on contracts that are way too long.
