Now things are getting personal.

After a week of relatively good-natured taunting between the Giants and Eagles that included a viral photograph, a team-produced video, an assertion that last year's division title was a bit hollow and a mathematically challenged theory of what the Eagles' record could be, one of the players is now calling into question the intelligence of an opposing coach.

Let's read that again: One of the players (who won't even be participating in the game Sunday night) is calling into question the intelligence of an opposing coach (who has won two Super Bowls and likely headed to the Hall of Fame).

Eagles center Jason Kelce, who is injured and will not play Sunday, was asked in a radio interview on WIP in Philadelphia on Friday morning about Jason Pierre-Paul's assertion that the Eagles are 4-1 but could be 0-4.

"Well, my response to that is, I don't think Jason Pierre-Paul is smart enough to come up with that statement on his own," he said. "I think he's the type of guy that just reiterates what his coaches have been telling him. So I'm a little worried about Tom Coughlin's math because I feel like maybe that's where it was screwed up. Maybe it was just relayed to him."

Kelce was asked to clarify if he meant to say that the entire Giants team is not smart.

"That is correct," he said. "They are a good football team, but yes."
