When Hunter Sharp was in his second season at Antelope Valley College in California, he and several teammates were visited by an assistant coach from Utah State named Mark Weber. As Weber went through a line of players shaking hands, Sharp knew what the coach was doing. “He wanted to see how tall you really were and how big your hands were,” Sharp said. So as Weber approached Sharp, the young wide receiver rose from his chair and slyly stood on the tips of his toes, opening his hand wide as he met Weber’s hand shake. “It’s nice to meet you, Coach,” the 5-foot-11 Sharp said with the confidence of a 6-footer. Weber indeed gave Sharp a shot at Utah State, and he’s turned it into a chance to show what he can do on an NFL stage. The Broncos signed Sharp off their practice squad Wednesday and told him he’ll be active Sunday when Denver visits the Los Angeles Chargers without the services of receivers Emmanuel Sanders and Isaiah McKenzie, who are nursing ankle injuries sustained Sunday.
