Since he has now stated that he is only looking to go year to year, this becomes very clean. His numbers are good and probably the most important thing for an older player, he was still playing well at the end of the season. He played in all 16 games and compared to 2017 he had better stats in most categories (sacks, Int, passes defended, tackles for loss; almost all but forced fumbles).
On the other hand time catches up quicker than you expect. So... his salary in 2018 was basically $3.1M considering bonuses. What is fair for 2019? Looking at the increased cap and weighing against his increased age, I would go in around $3M. Yes there is a risk that he hits the wall but the loss in that case is not even as bad as the risk we took on Corey Coleman. We ate $3.5M in cap and a 7th rd pick on that. So, something in the $3M range, give or take a little, seems like a no-brainer??
