Well, he did have 7-8 sacks.....

and he's totally raw. Not sure if he has only just used his speed as an attack. He could make strides in his 2nd off season, but like you I'd like to get an Edge in FA to go with him. We do have some strength in depth there with 2 or 3 guys getting some time this year behind him and Hoecht on the other side. Keep Hoecht, move him back to the line to replace Murchison.
