I reckon the Sheedy comparison is apt, and coupled with how much of a competitor he is, I don't doubt his passion. In fact, when B. Gale, Club Captain, and 21 other players are before him in the dressing room--even after everything he has achieved--I still think he has them all covered for dog-with-a-bone-never-give-up-stick-it-up-em-I'm-going-out-on-my-shield will to win. Combine that with a growth mentality and young age for a coach.
I suspect that building another premiership team would deeply appeal to him.
