Doug Marrone has insisted that the Buffalo Bills still have a lot to work on, despite winning their first two games of the pre-season.
The AFC East side secured a narrow win over the Minnesota Vikings last night, having thrashed the Indianapolis Colts in their opening game on Sunday.
The team's head coach told reporters: "Obviously our goal coming into the pre-season is to win the game and our players did that today. I thought early on that our defense played very well, made some things happen.
"Offensively, I think that we had some tough field position. Shot ourselves the foot with penalties again and that's going to be something we need to address and take control of that.
"Still got a long way to go, we got a lot of things to work on. All of us, myself, the coaches and the players."
The Bills play the Washington Redskins next Saturday.
