2015 NFL Free Agency: Devin McCourty and Darrelle Revis are going to hit the market

The Eagles may have a shot at adding not one, but two top secondary pieces in free agency. The Patriots placed the franchise tag on kicker Stephen Gostkowski on Monday, which means that safety Devin McCourty and cornerback Darrelle Revis will be able to test free agency, according to ESPN's Adam Schefter.

McCourty and Revis are coming off a Super Bowl victory with New England. Both players are likely to cash-in this offseason, as they have been among the top defensive backs in the league for years. The Patriots still have a shot at re-signing both before the start of free agency on March 10, but their  agents may want to see how much they can get elsewhere.

McCourty would be a strong fit for the Eagles, as the team prefers safeties that can be used in man-to-man coverage. A former cornerback, McCourty's strength is coverage. The Eagles have plenty of cap space, so they may pursue McCourty to start opposite Malcolm Jenkins.

Revis is among the best cornerbacks in the league and is likely to be chased by several teams on the market. He would also be a great fit for Philadelphia but would also cost a lot of money. Again though, the Eagles have plenty of cap space.
