(AP) — Saints punt and kick return specialist Marcus Murphy had done his research, and wasn't about to fall victim to self-doubt after dropping to the seventh round last spring in the NFL draft. After scoring on a 74-yard punt return last Sunday, Murphy has left little doubt that he belongs in the NFL. [...] at 5-foot-8, 193-pounds, Murphy apparently lacked the physical stature to convince many scouts that he was sure-fire NFL material. All the while, Murphy was confident he was close to breaking a big return because of the potential he saw during several long kick and punt returns during the preseason, which won him the job to start the regular season.
