Alex Van Pelt doesn’t suffer from delusions of grandeur. The Buffalo quarterback has a handle on his skills and his value to the team. Sometimes, that’s not enough. For a handful of backup players on every club in the NFL, the union that was organized to protect their interests often prices them out of the market with the veteran minimum. That happened to Van Pelt last season before a training-camp injury opened the door to his return. “Exactly,” Van Pelt said. “I was like hey, my union is supposed to be out there helping me, and instead, it’s keeping me out of work.”
