You can't rely on one guy to win games. The same thing happens in Dallas. I mean, yeah, Romo can make some pretty stupid moves, but, he also has a team in front of him that doesn't always mesh together. When the team loses, everyone blames Romo. When the team wins, OMG ROMO HAD SUCH A GREAT GAME!1!!! I am pretty blunt when it comes to talking about how awful the Cowboys can be, but, blaming things on ONE person is not always the answer. Romo has messed up a few games with picks and sacks and whatever other bullpoop he can come up with, but, his team can also contribute to a loss when they make dumb plays. He isn't the only one who loses a game, his team loses as well....again, not saying he is not always at fault, he is quite good at getting interceptions at the absolute worst times, but, he is still not always to blame. Same with Keenum. I think one of the main differences, though, is that Dallas actually has some great players, they just need to make sure they are on the same page at times. Keenum has garbage to work with, pretty much. Can't put the entire blame on him, his team blows, and his coach is a dildo.
Romo has had some bad games where Dallas has won, and he has had some good games where Dallas has lost. Houston is definitely a case where the entire team is pretty much to blame for being poo and that is why they lose.
