"I had an incredible journey and experience in the NFL," Long said Tuesday on NFL Total Access. "It was like nothing I've ever done before. Met great people, done amazing things, but at the end of the day I wasn't able to hold up my end of the bargain as a football player. When you sign a contract and they say we're gonna give you X-amount of dollars, you gotta do your job and I wasn't able to be healthy enough and to perform my job well enough to protect Trubisky and get the running backs through the holes."
