Actually 5 tackles in 31 snaps is pretty good. After being signed late the Browns just havent given him any playing time. The Bears were never going to trade for a big contract edge. What they were looking for was added depth that will fill in as a rotational DE . Joe T-S best year was 40 pressures, 5 sacks, 7 TFL, & 7 QB hits and one forced fumble in 50% of the snaps.
He is 26 and signed for two yrs at 4.6 mil that can be cut at any time for no dead money. As someone said, low risk, low cost. If we can get 4 or 5 sacks out of him in 9 games he will have been well worth it.
