On paper, I would say they are the two favorites to make it to the NR final. However, Westfield could have something to say about that.
I have not seen LB at all this year but I do think the fact that they have added more of a running game than in the past will only help them. On the flip side, I am not so sure about their defense being as good as what it was hyped to be in the preseason, from what I have heard, despite the low overall PA average. Other than the Centreville game, when CV was really struggling and turned the ball over quite a few times and only scored one TD, the teams they have shut out are either pedestrian, or really, really bad.
The SC-WF game was early in the year and the suspensions did affect WF, yet they only lost by 7 (and one of the SC TDs was a very,very badly blown coverage). I know WF would love to get another opportunity. WF has not been able to establish a strong run game all year, but they do get production in spurts and they do have the ability to hurt teams with the pass. And then there is the WF defense. SC has not played a defense remotely close to the WF defense, so if a few simple things from the first game go one way or another it could easily result in a different outcome should the two meet again. But that cannot happen until the 3rd or 4th round (SC-WF) and both have to get that far first.
Edit: One caveat. What I said above is based on what I have heard so far. Friday's SC at LB game will tell a lot, and might change my opinion if one team gets the better of the other by a significant margin. Either way it goes this LB-SC game is one of the better ones this season.
