The Colts have yet to guarantee that they will take Andrew Luck with the first overall pick in this month's NFL Draft. That has led to some speculation that they could shock the football world by taking Robert Griffin III. Indianapolis owner Jim Irsay tweeted on Saturday that while Luck is the favorite for the pick, the team hasn't made a final decision. "ColtsFans,roster reshaping exciting n producing a very physical MONSTER!Things have always pointed toward #12 but eval process is OpenMinded," he wrote.
