In an intriguing twist of fate over the past week, Indianapolis Colts QB Andrew Luck lost the architect of his offense from his phenomenal rookie campaign -- Bruce Arians, who took the HC job in Arizona -- but gained the man who had guided him at the tail end of his career at Stanford -- Pep Hamilton, who left his job as the "Andrew Luck director of offense" with the Cardinal to take on the OC post under Chuck Pagano. So what changes should we expect out of Indy's offense as a result of that substitution?
