A source tells the Boston Herald that free agent TE Dustin Keller's "knee is healed." It would be an amazing feat just eight months after Keller's catastrophic preseason injury, which included tears of his ACL, MCL, and PCL, and dislocation of the knee. Keller visited the Patriots on Wednesday, where he'd be an excellent fit on paper. We still have a hard time believing he's 100 percent.
