ST. JOSEPH, Mo. (AP) — Clyde Edwards-Helaire and Isiah Pacheco were chosen by the Kansas City Chiefs on opposite ends of the draft spectrum, one of them a first-round pick with the accompanying expectations and the other a seventh-round longshot. Midway through training camp, they might as well have been picked one after the other. That’s because Edwards-Helaire, the incumbent-if-injury prone starter, and Pacheco, the unheralded rookie, have swapped first-team reps on a near-daily basis. And while veterans Jerick McKinnon and Ronald Jones II are fighting for roster spots of their own, the competition between Edwards-Helaire and Pacheco has become must-watch stuff for fans at camp.
