10 worst NFL FA value signings

If you're going to pay a defensive tackle as though he's a quarterback, you might as well do it for a consistently dominant one in his prime. That's what the Miami Dolphins did when they signed Ndamukong Suh to a deal featuring $59,955,000 fully guaranteed at signing. That was nearly $6 million more than Aaron Rodgers' contract carried two years ago and more than double what Mario Williams commanded in his blockbuster deal with Buffalo in 2012.

It is probably impossible for a defensive tackle to justify the investment Miami has made, but Suh is still a fantastic addition to the Dolphins. His massive contract, though, landed him an automatic spot on my list of "overpays" since the NFL free-agent signing period opened about a week ago.

Some expensive deals make sense for one team and not for another. Contract structure is another key and often confusing variable. Some of the other players listed will not begin to approach Suh's impact from a financial standpoint, but they could still be high risks simply because they won't begin to approach his production, either. The cornerback market is a great place to begin, but only after dealing with a contract casting a shadow over South Beach.

Here are my top 10 overpays in free agency this offseason:
