1. Something is going on with Joe Flacco and Jim Caldwell. Something good. The quarterback and the new quarterbacks coach are clearly clicking. Maybe it's that they both share easygoing, steady demeanors. Maybe it's Caldwell's attention to minute details and his "knack" -- as offensive coordinator Cam Cameron called it -- for teaching. Regardless, the two are really feeding off each other and Flacco has been enjoying some of the best practices of his career. Receiver Anquan Boldin couldn't have drawn up a better pass than the one Flacco lofted to him in the back left corner of the end zone during a red-zone session Saturday. Granted, it's early, and yes, they're only practicing, but with Flacco coming off a season in which he posted a career-worst 57.6 completion percentage, it is something.
