I think Millen annoys me more. He speaks so authoritatively while saying absolutely nothing, he frequently gets plays wrong while a slow motion replay is on the screen (e.g. "That puck went right through!" while the replay clearly shows a deflection) and he calls every single goalie ever a battler - it's like the only "analysis" he knows how to give.
Romanuk is terrible too though. He frequently gets names wrong, frequently seems completely unenthused by scoring chances and always has the most bizarre, awkward questions for Millen. I don't hate his voice as much as others, it's just the things that come out of his mouth.
