Speculation whirls around new referee hires
This could be an interesting angle to follow. I'd guess perhaps less penalties (speedy games) or perhaps more penalties (slower games) as far actual game length. Of course if they happen to be assigned to young teams, you would expect more penalties vs a much more veteran team. It would take at least a month or two to see if there is a trend of any type to follow for the new hires.
