I think Collinsworth does a pretty good job overall. I liked the Michaels/Collinsworth duo better than with Tirico, but Al Michaels is one of the best to ever do it.
Cowboy fans seem to hate every announcer out there and always say they hate Dallas. Even Aikman gets accused of bashing the Cowboys, but for the most part I've never really felt that way.
Last night was one of the toughest situations announcers could be in. A blowout is never fun to call, and you often have to remember that you have two fan bases as well as the national audience to cater to. You still have to talk about the team on the losing end, which is difficult to do, but you need to keep as many of those fans engaged for ratings purposes, plus you have to remember that as an announcer you don't want to full on bash the losing team as you'll be calling another game of theirs at some point and you want the pregame interviews and player/coaching insight that comes from those. Playing announcer, especially for a prime time game is a lot more of a political game than many believe it to be.
