Five things to watch

Proper tackling: With Bulaga out, Kyle Murphy and possibly Jason Spriggs are going to have to hold down the right tackle position and probably attempt to block all-world linebacker Von Miller. It’s a good sink-orswim test, but not the kind you want with Aaron Rodgers’ health at stake. Coach Mike McCarthy has to give them help, doesn’t he? What’s next: In the exhibition opener against Philadelphia, Dom Capers blitzed like crazy. In the second game against Washington, he loaded up to stop the run. In this game, it’s a good bet he goes with a lot of his “nitro” defense, the one that features safety Morgan Burnett as a linebacker. This is the last chance for the starters to work on it in live action. Mile High hang time: In two games, rookie punter Justin Vogel has punted 13 times and averaged 45.6 yards gross and 44.0 net. He has landed seven punts inside the 20. The Packers would kill for those numbers during the season, but the fact is Vogel has gotten some good bounces, benefited from excellent coverage and not been consistent. He needs to destroy the ball in the high altitude to show he’s capable of being the starter. Back to back to back: Running backs coach Ben Sirmans said he really wanted to see seventh-round pick Devante Mays get a shot at running against the opposition’s No. 1s, but to do that Mays will have to play with the Packers’ No. 1s. Ty Montgomery is first up and then Sirmans will have to decide whether to go straight to Mays or follow his camplong progression of using Jamaal Williams second. Middle men: So far, the coaches have favored Blake Martinez and Joe Thomas as their inside linebackers in most nickel and some base situations. Martinez looks far more fluid than a year ago and not as out of control when he plays the run. The big question is where does Jake Ryan fit in? He and Martinez fit best on early downs, but with the amount of “nitro” being played, it remains to be seen where Ryan stands.
