Not lockstep per se but they respect the boundaries of each position and allow them to do their jobs without interference. That's the key thing that's made our turnaround possible.
O'Shea's first few seasons weren't stellar and there was a lot of the typical knee jerk stuff being posted on various forums. Miller stayed the course. Walters stayed the course. They allowed coach to grow, build and develop the culture we have now. It's paid huge dividends in terms of our competitiveness and respectability as an organization.
That said (and as other's have noted) O'Shea has always made a few head scratching decisions that gives us fodder to keep chewing on.
