Nobody this season has been more critical of PL refs than me. That being said, I was at the game and I didn't find it to be that horrendous. Yes there were some bad calls. The fourth on McNaughton in particular was rediculous. But you know, the calls went both ways and there weren't any calls that really changed momentum or the complexion of the game. This really wasn't the type of game that the refs had much of an impact in deciding the outcome.
As for the Lehigh outburts, they also ignored a Badmus outburst where he spiked the ball 20 feet in the air.
