Don't really agree with some of that, especially about the 2nd half. Chip Kelly has NEVER been one to pull back on an offense, and he wouldn't pass up his first chance to do so in the NFL, he would have made a statement and scored 100 if he could.
The defense was finally getting some rest and was catching up to the offense, and catching on to how it was run. It's funny he shows that play of Vick running since that's the one he got hurt on, and it took away much of their read option power since he couldn't run as fast. (Kinda like Grif in the first half) Then WAS started keying in more on McCoy and worried less about the deep pass (did they throw the ball more than 10 yards in the air all night?)
They were clearly not rushing to call plays. I don't see how you can think otherwise. They went from calling plays with 15-20 seconds left on the clock to consistently calling plays with under 10 seconds on the clock. It's the NFL not college. Chip Kelly is smart enough to realize that.
