When life throws you lemons, you make lemonade. I think McCarthy adjusted his playcalling to suit what he had (something I had a bit of an issue with a couple of years ago) and I had no qualms with it.
As for the throw in the redzone at the Buffalo game, I was initially ticked off UNTIL I found out that play had been quite successful for the Pack. Last year, Brett had something like 8 TDs and 1 INT in the redzone, so it wasn't as if that play hadn't worked before.
It was a gamble, but a gamble that had paid off for us. In the redzone, Driver got single coverage, and to be honest I don't mind McCarthy trying to exploit that. Driver is a great WR, and having him in single coverage is something you should try to take advantage of.
A run wouldn't have been a bad call (well ok, it should have been the preferred call), but throwing to Driver was the next best thing. It wasn't like it was a terrible move, it had worked before and trying to exploit the other teams single coverage on Driver is something I can understand.
I'll be interested in seeing how the playcalling changes based on O-line's improved play (which should occur).
