The Giants were playing him at safety.

His best years were LILB for the Cardinals.

So to ask that question of who he was playing for is legitimate.

At minimum he can be a rotational coverage LB and a highly athletic special teamer.
With a new system and coaching maybe push for a starting job.

Any nfl linebacker that is 6-4 238# and can run a 4.39 forty with a 1.51 ten yard is a tremendous athlete.
Has a 10 or 9.7 RAS score depending on where you look and 26 years old you have to do your diligence and add him for the right price.
