Darrelle Revis, Golden Tate, Julius Peppers, DeMarcus Ware and Justin Forsett are ranked as the top offseason acquisitions of 2014 by Mike Sando.

Revis has re-established himself as one of the best corners in the league and currently ranks second in Pro Football Focus grading at the position. The Patriots acquired him for a $7 million cap charge this season.

Emmanuel Sanders, Darren Sproles, Steve Smith, Brandon Flowers and Jared Veldheer are ranked 6-10.

Haloti Ngata has been suspended for the rest of the regular season for violating the league's policy on performance-enhancing substances, the team announced Thursday.

Ngata, a five-time Pro Bowl defender, received a four-game suspension from the NFL, and he's eligible to return for the playoffs if the Ravens make the postseason.

"I made a mistake, and I own this," Ngata said in a statement. "I took Adderall and take full responsibility for doing this. I am deeply sorry and broken up over this. I let down my family, my teammates, Ravens fans and myself. My hope is that the Ravens make the playoffs, and I believe they can do this. And, then I can come back and help us win."

The Baltimore Ravens will turn to second round pick Timmy Jernigan to replace Ngata at defensive tackle.

Ray Rice wants a second chance in the NFL and hopes that any team interested in signing him will "look deeper into who I am."

Rice said potential suitors would have to understand that he and wife Janay "had one bad night."

"They would have to be willing to look deeper into who I am and realize that me and my wife had one bad night, and I took full responsibility for it," Rice said. "And one thing about my punishment and everything going along with anything that happened is that I've accepted it. I went fully forward with it. I never complained, or I never did anything like that. I took full responsibility for everything that I did, and the only thing I can hope for and wish for is a second chance."

At least four teams have expressed interest in Rice, including the Indianapolis Colts and New Orleans Saints.
