Indianapolis's Bjoern Werner has dual elgibility, he's taking over Robert Mathis's spot at OLB and Mathis is moving to Freeney's old OLB spot.
Trent Cole is also listed at DE even though Philadelphia has moved to the 3-4 and has him playing sorta a Suggs role where he plays OLB in the base and DE when they go to a 4 man front in the nickle/dime. San Francisco does that with Aldon Smith pretty much, with Justin Smith kicking inside lining up like a DT.
Those are the two I noticed. I went through the entire player database a couple days after yahoo opened so maybe there's more by now or some I missed. I plan on checking again before my draft in August when I do last preparations.
