Indy sinks the defending NFC champions, the entire NFL Nation responds by hailing their 'new-offense', and I'm like "Well, I'm certainly down for some variation. Could have used it last week." In other words, I don't think Indy's offense has drastically changed; they're simply playing against opposing gameplans. San Fran put everything into stopping Andrew Luck because the Colts don't run the ball (see: Miami), and Indy's gameplan changed accordingly. Their gamble – to lengthen their drives and control the game – paid off perfectly.
Had they employed their run game more consistently against Miami, Indy would probably be 3-0 at this point. Still, it is encouraging that, after years of predictable gameplans, the Colts finally turned a perceived one-dimensional offense into a successful system. Hence, they're exactly where everyone expected them to be.
This week, Bleacher Report's Chris Trapasso writes a solid article on how, in fact, Indy's offense (under Pep Hamilton) has changed somewhat from last season. He ties in Luck's Stanford days and Hamilon's obvious influence on their offensive changes.
While the hiring of Hamilton was obviously the most instrumental aspect of installing the Stanford offense Luck was familiar with and successful in, general manager Ryan Grigson supplemented Hamilton's addition by making the personnel decisions necessary to establish the new attack.
Ahmad Bradshaw was added in free agency to give the running game a boost between the tackles, and his pass-protection prowess is a huge plus after the punishment Luck took as a rookie.
Trapasso illustrates strong points, mostly tying recent additions to their newly-successful rushing attack (eg. Gosder Cherilus). While I remain reluctant to think of Indy's offense as a totally different version of last year's squad – they still have minimal pass protection, a flawed defense, and a streaky run game – their ability to shift offensive strategies mid-game worked better than their previous efforts.
Keep with the run game, but – more importantly – keep defenses guessing.
