Cardinals head coach Bruce Arians revealed that he was sending plays into the NFL as he felt that his team didn't receive the benefit of some calls by the officials.
"Let's not be crybabies, man," Williams told PhillyMag.com. "I thought the refs kept them in the game to some degree at times. But it's football, man. It's about going out there and executing.
"If they came in here with a different attitude, maybe not so nonchalant, thinking it was going to be a cakewalk.
"It's football, man. Either you come in and win or you blame it on the refs. Don't blame it on the refs, blame it on your preparation that week."
The Eagles are 7-5 in their season following their victory at Lincoln Financial Field.
