For just about every NFL player, there's a lot on the line in training camp. Most are just trying to hang on to roster spots and keep their dreams of playing in the league alive. Others are trying to work their way into the starting lineup...or stay there.
And for some, there's nothing going on but the rent.
Granted, some contract-year players have little to worry about in 2018. Regardless of what happens this season, Oakland Raiders edge-rusher Khalil Mack is going to get his megadeal. So will defensive lineman Aaron Donald of the Los Angeles Rams.
