It's not really news. There's a reason Malcolm is the only All-Pro db on the Pats. He is still the best cb on the team, despite an up and down season. That's not a knock on Gilmore, who I like, but Stephon has mostly been about potential- still not fully realized. He's had some good games, but Butler is more consistently good.
I think this pair has a chance to be as good a tandem as Talib/Harris if they stay together. Really hope they find a way to keep Butler( probably wishful thinking), because I think next year that could be the best pair in the NFL. Can always hope.
