Shaq Lawson had a decent year in Buffalo recording six and a half sacks along with a forced fumble. He increased his sack numbers by two and half since just last year and with him being only 25 years old, he has plenty of time to keep improving.
The Titans should consider trying to get a guy like Lawson added onto their roster as a 2nd pass rusher along with someone else.
Derek Wolfe recorded 7 sacks and forced a fumble in just 12 games. Although he is 29 years old, he is still showing improvement by improving his quarterback hits by six, and doubling his quarterback knockdowns from a year ago. He also increased the number of quarterback pressures by eight.
Wolfe would make a great addition to a team that is trying to win now which is exactly where the Titans are.
Vinny Curry had five sacks last year with the Philadelphia Eagles and is available in free agency this off-season. He should be a relatively cheap pickup due to being 31, but, although he is getting old he would still be a great extension to the Titans defensive line along with another pickup. He increased his number of quarterback hits but five from last season and added five more solo tackles.
He had five tackles for a loss and the would go great on a Titans roster in addition to another edge rusher.
