Defensive end was cut by the Texans after 3 seasons. Prior to that he spent 4 with Rex Ryan on Baltimore. Not your prototypical 3-4 DE size at 6'3 278 but has the verasatility to be a solid role player in Ryan's defense once again and should come at a reasonable price.
He wouldnt be a bad choice as a backup DE or even give him the job ahead of Coleman. Would be a nice signing for depth.
Weaver went to high school near me and played for a rival school. My brother got to play against him. Just wanted to add that irrelevant info.
The more players who are familiar with the scheme, the less traumatic that adjustment period will be.
