Well, they have been the 2 starting LB's that are a part of a much improved pass defense and overall stronger pass rush than last season.
We have definitely taken a major step back in run defense with these two, but our pass defense and pass rush (as a result of them being able to consistently cover just a little longer) has been helped by their addition.
I've been pretty critical of both, but it's a trade off, they're not terrible, they're just better in ways that are less appreciated (not to mention this is a new system for both and both are playing better now than at the beginning of the season).
