My theory is that rbny doesn't have the fitness level they had in previous squads. I noticed that we look gassed by the 70th minute.
I actually think the way we play is part of the reason we've had some slow starts to the season since we started playing Ralfball (including under Marsch). You need to be fit to play the way we play now, and the best way to develop that fitness is through games, rather than training. That takes time.
We've also had some exceptionally strong finishes, too (such as last year).
