Some impressions I took from the game-
Positives
Cam Newton- Played very well, I think. The Dolphins defense wasn't great (they got no pressure upfront and left some gaping holes in the secondary), but Cam took advantage of what he was given and moved the ball well down the field.
Panthers defense- This was just a preseason game, so excuse me if I seem a little over enthusiastic, but the defense looked good. They were consistently getting pressure on Tannehill and were pretty good against the run too. Luke Kuechly was the standout man for me, he was strong in pursuit and was able to stop a good number of plays on the night. The secondary was decent, but their job was made much easier by how well the d-line played.
Negatives
Ryan Tannehill's Offensive Line- When you have a rookie QB behind you, your job as an offensive lineman is to do your best to make sure he's comfortable in the pocket. The Dolphins' o-line didn't do that tonight. They were beaten (badly) by simple four man rushes time after time and never gave Tannehill the time to operate in the pocket. They also didn't get much push, so the rushing game never was able to get off the ground.
Ryan Tannehill-When you spend at least 75% of your time in the game firmly planted on your ass, it's got to be a bad game as a QB. Granted, it wasn't his fault that his offensive line never left Miami, but still. I think Tannehill has all the tools to be a good QB, but this wasn't a night to remember for him.
Replacement Refs-Ugh. The refs were...terrible as always. Bullshit holding penalties all over the place (no, refs, good block does not equal holding) and at times the refs looked like chickens with their heads cut off. Some of the guys behind me were joking that they let the first ten fans in the stadium call the game. Based off of those calls, it wouldn't surprise me.
