Trent Cotchin as off-field mentor helped too. I believe the players said he helped them have the proper mindset in finals and the GF.
Not a coincidence that they never gave up and ground teams down to win like we did in our flags years. In previous years Lions took the lead and choked it most of the time.
I'm sure he has an impact, but they were a kick away from a flag while Cotchin was still technically on Richmond's list. Suspect the turnaround pre-dated the move by some time.
