Even though this is the dead period on the NFL calendar, the quest for improvement never ceases. Lions GM Bob Quinn will continue to explore every option available to make Detroit more competitive. That includes the ongoing free agency options.

Note that none of these players are likely to sign with Detroit — or anywhere else — before training camps begin next month. Here are five I would like to see the Lions strongly consider.

Connor Barwin

The veteran outside linebacker is well-versed in the Patricia style of defense. Barwin has played the rush backer role in a 3-man or hybrid front in his entire nine-year NFL career.

The 31-year-old Detroit native (Jesuit HS) bagged five sacks for the Rams in Wade Philips’ version of the 3-4 front in a part-time role. Barwin had five the year prior in Philadelphia in Bill Davis’ version, which also required him to have more run defense responsibility. At his Pro Bowl peak in 2014, Barwin netted 14.5 sacks and swatted down five passes.

He’s not likely to hit double digits in sacks again, but as a smart, dependable and self-aware contributor, Barwin still has a lot to offer. His oddball personality would play well with both teammates and the local media, too.
