With the advent of no-huddle offenses designed to keep the ball moving fast and to keep a tired defense on the field there have been plenty of instances in recent years where a player or team has been accused of faking injuries to stop the action so a defense can catch its breath.

Remember this incident with Deon Grant from two years ago? Or when Cowboys owner Jerry Jones earlier this month said it was so obvious that some of the Giants players were faking against Dallas that it was humorous (it probably wasn't all that funny to Dan Connor who went on the IR list that next week).

It's gotten so bad that even when an opposing defender shows the slightest bit of pain on the field the home fans boo him like he's Costa Rica soccer player Joel Campbell taking a dive.

Well count Eagles coach Chip Kelly among those who disagree with the notion that players are faking. Or at least disagrees with the notion of calling out those defenders who are under suspicion.

“Never ever going to get into that” Kelly said via Phillymag.com when asked about the Chiefs penchant for cramping in last Thursday's loss to Kansas City. “We need to execute better and not turn the football over. That's the least of my worries right now.”

One of the Chiefs who struggled with cramps last week was cornerback Sean Smith who had to stop the game multiple times so trainers could stretch him out. And he could understand why Eagles supporters wouldn't be happy with them.

“I knew [the jeers were] coming ” Smith said. “Everybody thought I was faking but I had to get an IV -- I've got the proof right here” as he pointed to a bandage on his arm.

“It shows how fast-paced that offense is” Smith said. “It's crazy you can't really practice it. So when you see it for the first time you don't really know what to expect.”
