As I said above, Tyrone probably don’t quite have the raw material based on only one recent u21 All-i success in 2015. And their coach hasn’t found a different approach to the (very innovative one) he developed with his first teams. In fact no approach will make up for lack of great players. Therefore MH probably just being pragmatic in that a very consistent system allows his team to maximise what they have.
Look at Dublin teams 2005-2010. Consistent way of playing, relatively successful, never going to win Sam, did eventually take a trimming when they couldn’t get the intensity to point on a day against a great team at their very best, and when they were no longer big underdogs/when expected to step up to the next level (very similar in reverse this year).
Next stage was a new coach trying radically different approach(for his county), result: worse beating. But the raw material had accumulated, and the new approach bedded in, and so on. MH is right not to try some new approach without the material as it will lead to worse beatings. Days like the semifinal this year are one-offs and Tyrone will be at least very competitive with Dublin next time they play. They may well benefit from the shift in expectations.
Like Tyrone in 2010, when more of Dublins major players go over the hill they will be vulnerable to a young, hungry team with talent and a smart, ballsy, innovative coach.
