ENGLEWOOD, Colo. (AP) — If Joe Flacco stays healthy, it won't matter that rookie quarterbacks Drew Lock and Brett Rypien are greenhorns and incumbent backup Kevin Hogan has gotten off to a rocky start in Denver this summer. Hogan, who has started just one game in the NFL, back in 2017 for the Cleveland Browns, threaded an 11-yard TD pass to Noah Fant past two defenders Sunday that was easily his best throw of training camp. Before that, the fourth-year pro had been misfiring with no pressure, repeatedly overshooting open receivers with either a clean pocket or in 7-on-7 periods where there was no pass rush at all. That was an alarming development for a team that lacks experience behind Flacco, the 34-year-old QB the Broncos acquired from Baltimore in the offseason. "I saw some good throws out there today" from Hogan, coach Vic Fangio said.
