IMO, is this years version of Greg Ellis.
I see him as a complete DE. He will be equally effective against the run and the pass. He won't be a huge producer of sacks, but he will create a lot of pressure on the QB. He will give you everthing he has on the field and be a leader in the lockerroom.
I also have a feeling his impact will not be obvious, nor will it be appreciated. He will merely come to work, put on his hardhat and be an anchor for his side of the line week in and week out.
