Combination of TT, MM, AR and luck. TT has done well providing supporting cast and key players, MM manages the program well and calls a good game, AR becoming a master at his craft... and then luck that the division has been relatively weak for a decade, ensuring that winning it has been within reach year after year. It all goes together and if one of those links was weak the whole chain would break.
Murphy I don't know about, his impact will be seen in the long run. On the one hand he's been doing a lot to continue to develop local team revenue grows. On the other hand, who knows yet what the long term impact will be on the GB community of that team-oriented development. If nothing else I think he's succeeded in his main job, which is stay the heck out of the way while the football people do their thing.
