The Eagles superstar has a fair reason to be upset.

The Eagles appear committed to expanding Barkley's role, and the legend thinks that will pay huge dividends.

Most NFL teams will have two or three days of joint practices throughout the preseason to break the monotony. Some players are fans of them, and some are not. Saquon Barkley is the latter. Joint practices are held so teams can see how players go up against opponents they don't see every day in practice.

Eagles running back Saquon Barkley came away from Thursday's joint practice session impressed with how the Patriots are looking.

The Eagles star sees value in facing unfamiliar opponents during camp, but he also believes joint practices too often drift away from football.

The Eagles and Saquon Barkley are riding the run-game rollercoaster in training camp. Their practice with the Patriots on Thursday didn’t provide much of a thrill in that regard.

These three NFL stars could present immense fantasy football upside at the No. 12 overall pick in drafts.
