The quicker people get use to the fact that Joey Porter and Matt Roth are our starting OLBs, the better. As I've been saying, Porter was a WOLB in Pitt and we moved him to SOLB with disastrous consequences. JT is gone so moving him back should have been a no-brainer, but we seemed to *****foot around it. Meanwhile, for all the crap Awsi Dooger talks about the idea, Matt Roth is the best OLB we have not named Joey Porter. Charlie Anderson appears to be your typical flash in the pan type that has one good week of TC practice to get people excited (as they tend to do with speed rushers) and then does nothing since (see Abe Wright). The best work I've seen Quentin Moses do has been as a down DE, which isn't saying a whole lot because he has a long way to go.
Will Matt Roth win any Pro Bowls at OLB? Doubtful. But he's a strong presence against the run and he's a 4.80 kind of speed guy with decent agilities, and just because he never developed a speed rush doesn't mean he can't be almost adequate in coverage...and so far that's what he appears to be.
The biggest weakness for him as an OLB is pass rush, but as a SOLB, that's not as big an issue anyway. Joey Porter's got the better pass rush so he should be at WOLB.
BTW that article does have somewhat of a false premise, I think. Judging by those first couple of sentences, anyway. Langford and Merling started at the DE spots in the first preseason game, and Roth started at SOLB in the first preseason game as well. The only difference from the first game to the second is Porter was out injured in the first game and in this game he came in and played WOLB.
