Training camp is over and teams around the NFL have shifted into regular-season mode. The third preseason game is basically treated like a watered-down regular-season week.
That means most of the evaluation period is over (some of it never ends). The roster is being finalized now, and there are very few opportunities left to make an impression on Scott Piol, Romeo Crennel and the other coaches.
Training camp always gives rise to a few unexpected stars, but there always are a few players who disappoint and leave the coaches and fans wanting more. The Kansas City Chiefs have several players that had impressive training camps and several others that had poor training camps.
