The Eagles on Thursday claimed RB Trey Sermon off waivers. ESPN's Adam Schefter reports that the team had previously discussed a trade with the 49ers. Sermon took less than 2 full years to bust his way off the roster of the team that drafted him in Round 3. So it's tough to bet on a big impact from him. But he's immediately the heaviest RB in the Philly backfield. We'll see whether than can make Sermon a quick factor in short-yardage situations.
