the real refs are fine. they've made some iffy calls but it's not nearly the same magnitude nor level of pure game play issues as the replacements.
the replacements couldn't keep the game going at a suitable pace, players were trying to get away with anything and everything(and rightfully so) and way too many issues were going on where coaches had to go off on them.
there is no comparison to the real vs replacement. the real ones are much much better.
