What the hell was that?

The Colts opened a new stadium this year, Lucas Oil Stadium, which the denizens of Indianapolis are ecstatic about. It's a fantastic stadium (for Indianapolis) and they have a pretty decent team to fill it. They were lobbed a softball in week one in the Chicago Bears who were pretty awful last year.
And they blew it. What?! To this guy?Pathetic. But the good news is, they know this was pathetic, and they know exactly what their problems were. They were threefold, which is good, because that's as far as I can count.

1) Peyton Manning was not up to speed. He hasn't practiced much and didn't play at all in the preseason after offseason surgery to remove an infected bursa sac. I'm not sure what a bursa sac is, but apparently you don't want one of them in your knee. But after a couple full weeks of practice, he should be back up and ready to go. I hope.
2) Without Jeff Saturday, the offensive line is not so good. There is no timetable for his return, unfortunately, but perhaps with a little more playing time, the line can hold together and prevent any ferocious pass rush. Or maybe the Bears really were that good with their blitz.
3) The run defense is abysmal. I don't know what to say about all this. Usually it's not a problem because opponents need to play catch up throwing the ball. At least the Colts don't play anyone with a good ground game any time soon.... oh.... wait.

Hopefully Manning can shake it off and turn it around so the onus isn't on the run defense next week here in Minnesota.
