as Caldwell wrapped up his first press conference of camp, just a couple hours before he would address his team for the first time on this very stage, the strangest of all sights emerged. An actual smile.
The Lions have stockpiled 2016 draft picks over the past few months. They're sitting on about three compensatory picks, after losing Ndamukong Suh, Nick Fairley and Kellen Davis in free agency. Two of those should be third-rounders.
Success is ephemeral in the ever-churning NFL. As Caldwell says, the average roster turns over around 30 percent every year. The Lions have undergone several changes of their own, and change always adds some uncertainty to the mix.
