If there's one thing Philip Rivers likes, it's an undersized receiving back. Over the last decade, players like Darren Sproles and Danny Woodhead have built their careers running wheel routes around frustrated linebackers and providing a security blanket for the quarterback. Last year it was Ekeler's turn to fill that role, and while it took the undrafted rookie a while to earn Rivers' trust, by Week 10 he was an integral part of the Chargers' attack, catching 12 of 13 targets for 171 yards and two touchdowns over a four-game span before a broken finger cut short his productive run. At 5-10, 200, Ekeler isn't going to supplant Melvin Gordon on early downs, but he runs with some surprising power for his size and can contribute a bit on the ground, even if his bread-and-butter will always be catching passes and making defenders miss in space.
