Because Nicks went back to his true form that we saw in 2021/22.
He's a defensive coach, the first thing defensive coaches think. If you play quick and use the corridor you can turn it over and leave yourself vulnerable for easy scores against. So you play slow, go down the line, if you don't mark it you kill the ball, set up for a throw in and chuck numbers at the contest to win it.
They saw the numbers last year. Great at scores for, bad at scores against. We gotta stop getting scored against, so let's slow it down, don't let the opposition get good field position and keep it in a contest where we can win an arm wrestle.
Would rather double down and back ourselves to outscore them.
