Ranking teams that regressed after first surge of NFL free agency

Is Butler on his way out following Gilmore's arrival? (1:22)

The 2017 unrestricted free-agent market hit its 100th agreement on Tuesday, when Eddie Lacy signed a one-year deal with the Seattle Seahawks. I already looked at the most improved teams so far, so it's time to hit the inverse today: Which teams are worse off through the first week of free agency?

One team that isn't on this list now but might be next week is the New England Patriots, who have suffered some key losses on defense and could still lose linebacker Dont'a Hightower (Update: Hightower is returning to the Patriots) and restricted free-agent cornerback Malcolm Butler. Hightower is actively shopping for a team that will pay his $12 million per year asking price, and Butler could move on after the Patriots chose to sign Stephon Gilmore from the Bills and give him $40 million guarantees.

The New England defense also has lost linemen Jabaal Sheard and Chris Long, along with No. 2 cornerback Logan Ryan. That's a lot to replace, even as the offense got better with the addition of Brandin Cooks. The league's top defense in points allowed in 2016 (15.6 per game) is weaker than it was when it ended the season.

Here are the five teams that have been hit the hardest:
