Lane Johnson believes he is one of the two or three best offensive tackles in the NFL. Right side, left side, east side, west side, any side. He’s going to have an excellent opportunity to make his case in the Eagles’ next two games, beginning Sunday, when he faces off against perhaps the league’s premier edge-rusher: the Broncos’ three-time first-team all-pro, Von Miller. Then, after the bye week, he’ll do battle with the NFL’s current sack leader, Cowboys defensive end DeMarcus Lawrence. If he can manage to neutralize both of them, the fifth-year right tackle finally might persuade enough of his peers that he deserves an all-expenses-paid trip to Orlando in January for the Pro Bowl. Miller and Johnson have never faced each other. The Broncos and Eagles played each other when Johnson was a rookie in 2013, but Miller was serving a six-game suspension at the time for violating the league’s substance-abuse policy. But their cups seem to runneth over with respect for each other. At least they did this week.
