At 36, Josh Johnson is the oldest player on the Broncos’ roster by a couple years. But he doesn’t see his journeyman’s tale ending anytime soon. “I want to play at least until I’m 40,” Johnson said. “I’m going a year at a time, then I’ll re-evaluate again after 40. But until then, I’m trying to keep it going as long as I can.” For now, Johnson’s focus is on Saturday, when he’s expected to get his second preseason start for the Broncos when they play at Buffalo.
