The problem with NFL officiating isn't so much that the refs are bad, it's the complexity and subjectivity of the rules. It's hard to officiate an NFL game. It's a fast game and a lot of bing, bing plays. We can see things on TV that the refs on the field may not necessarily see, or at times because of positioning they may think they see something that they don't, like the phantom face mask. You could review every play and probably make calls that aren't called or reverse calls that are called, but then you're looking at 5 hour games.
The Ravens have played two sloppy games. They lost this game today because they couldn't close it out after getting out to a 10 point lead in the second half. The defense let the Raiders make all the plays they had to make instead of getting stops. The Ravens can point fingers at the refs, but they need to look at themselves first.
