Buffalo coach Rex Ryan likes his organization’s aggressive play during free agency and goes as far as saying the Bills are closing on the Super Bowl championship New England Patriots.

In the last week, the Bills traded for running back LeSean McCoy and quarterback Matt Cassel, and signed wide receiver Percy Harvin, fullback Jerome Felton and quarterback Tyrod Taylor. They also brought back, among others, defensive end Jerry Hughes.

On the other side, the Patriots haven’t made many big moves and have lost some key players.

“I feel pretty good about what we’ve added,” Ryan told Toronto’s SportsNet 590. “I think the conference really got stronger. If anything, it currently doesn’t look — if you can say winners and losers in free agency — obviously New England had to cut quite a few players.

“So obviously they don’t look as strong as they did. I certainly hope they’re not. They just got through winning the Super Bowl. But I believe the rest of the division really has got stronger. I don’t think there’s any doubt about that. I truly believe that we got stronger.”

The Patriots lost players from their championship team, including cornerback Darrelle Revis to the New York Jets. New England also did not pick up 2015 options on defensive tackle Vince Wilfork and cornerback Brandon Browner, making them free agents.
