More injuries on the OL

[sportscurmudgeon]

Here's a tidbit I ran across:

The Indy Colts are starting their fifth different offensive line combination in the last six weeks because of injuries across the line. That's not something QBs wish for!

However, Peyton Manning has been throwing TD passes at a record rate and he has only been sacked a half-dozen times all year. How is that OL getting it done?
