Some quick highlights of Bill Belichick's prepractice presser today. The Eagles, including just-returned wideout Riley Cooper, are facing the Pats in a joint practice at NovaCare:

*Belichick said the practices provide a "great opportunity" to see something different amid the monotony of training camp. "It's good for everybody. It's good for the young guys, good for the old guys, good for the old coaches."

*Belichick said he was "excited to be here," a statement belied by the famously dour coach's expression.

*Belichick praised Chip Kelly as "a solid coach and a solid guy. I've always had a lot of respect for him ... a very innovative, creative guy, he's smart," but Belichick played down the friendship between them and its importance in the decision to hold joint practices, something the Patriots have done several times in the past with various teams.

*Belichick said he "personally never felt it was that big of a deal" to switch from a 4-3 to a 3-4. He recalled doing so as defensive coordinator of the Giants. He noted that Lawrence Taylor still rushed the passer most of the time, either way.

*Asked what Kelly does offensively that's challenging, Belichick said: "We're going to find out."

*Belichick said when it comes to officials setting the ball and trying to run a hurry-up offense, whether there's an impediment varies from crew to crew and from week to week.

*Belichick was asked if he felt the need to say anything to his defensive backs about practicing against Cooper, who just returned from sensitivity training after a video surfaced last week in which Cooper used the "n-word." "No," Belichick said.
