Rotated, in all likelihood.
But, I wouldn't count out the possibility of him becoming a full time starter at LOLB. Right now Matt Roth is working back with the DL position group. That has to raise a few eyebrows.
The Dolphins picked up Gibril Wilson, one of the best run stuffing safeties in the league, and they're moving to a Quarters defense that allows them to show a 9-in-the-box look on run downs.
Meanwhile, Jason Taylor has clearly been working within the Dolphins' off season weight training system and looks a lot bigger than I remember.
It could all be enough to warrant him at LOLB because what the Dolphins lose in run defense going from Matt Roth to Jason Taylor, they may gain by having Yeremiah Bell and Gibril Wilson working in tandem within the Quarters defense. Then they could take better advantage of the JT and JP tandem in pass rush.
Getting one of those guys matched up on a back or tight end on a play-action pass is a lot more exciting than getting Matt Roth matched up on a back or tight end.
