Nate Dunlevy points out that the offensive line struggled against against the Vikings but made strides. Of course, they have an ace-in-the-hole:
It’s far too soon to make any judgements at all about Grigson’s efforts in rebuilding the offensive line. Until the Colts actually play their projected starting lineup together and in position, it will be a work in progress.
Fortunately for Indianapolis, the single best skill Luck brings to the table is pocket awareness that is in a category with the best in football.
