This month, offensive coordinator Cam Cameron and new quarterbacks coach Jim Zorn took Joe Flacco out to the University of Southern California, where he trained with a baseball pitching coach. The weeklong sessions focused on his throwing motion and the small muscles around the shoulder, all of which are expected to help Flacco's accuracy, arm strength and longevity. The hope is all of this hard work will result in a breakthrough season for the third-year starter. "I want Joe to be a championship quarterback," coach John Harbaugh said Tuesday at the NFL owners meetings. "There are terms like 'elite quarterback' and 'franchise quarterback.' All of those things are where we expect Joe to go. He does even more so than we do. You know how Joe is. He already thinks he is the best quarterback in the NFL." Harbaugh added, "But he knows that he's always going to have a lot of work to do. I know physically he needs to get stronger. Mentally, he needs to get sharper. Technique-wise, he needs to get more pronounced. But the expectation is to be the winningest quarterback in the NFL."
