Kawann Short or Star Lotulelei
Carolina is basically out. Carolina picked up the option on Lotulelei and drafted Vernon Butler in RD1 of this past draft. Short is a FA after the season and wants Fletcher Cox money, so somewhere around $15-17 mil. His '16 cap is only $1mil. Not getting to the QB much this year but had 11 sacks last year. He'd be a centerpiece under tackle in Dallas defense. Lotulelei might be available instead. He hasn't shown the rush capacity he displayed in college but maybe he's scheme cuffed.
Sheldon Richardson
Jets are also basically out. Jets have Mo Wilkerson on a big contract and Leonard Williams will be soon. Playing out of position at DE. Should be playing 3 tech. Manageable contract in '16 but option year in '17 goes up to $8mil. Had 4.5 sacks in '15, 8 sacks in '14. Spotrac says market value on a new contract would be around $13mil. Was suspended 4 games at the start of last year and 1 game to start this year.
Both trades probably start at a RD1 pick.
Lesser trade would be Willie Young with Chicago. He has 6 sacks this year with basically no help. Had 6.5 last year and 9.5 with the Lions in '14. Manageable contract and probably can be had for a 3rd or 4th and maybe throw in Escobar to make room. He's 31 and a free agent in 2019.
