In the last 3 years the Lions picked 23 people in the draft. Out of those 23, 21 are still on the team. CB Chase Lucas and RB Jermar Jefferson are the only two players cut, both were 7th rounders. I'd say that is a pretty decent success rate for Brad Holmes.
I thought that they would use DLine as trade capital for a WR. Sounds like a bunch of teams also were looking for kickers too so I guess they stood their ground with the guys they had. It'll be interesting to see who they pick up once they put Iffy/Okwara etc on IR.
