Jets safety Jim Leonhard is working hard to get back on the field, even though there is no guarantee there will be football this fall. Leonhard is making positive strides as he rehabs the broken leg he suffered during a practice session on Dec. 3. His rehab has been on schedule, just over three months after a metal rod was inserted into his leg. "They're letting me be a lot more aggressive with the rehab," Leonhard said. " "Until that bone has completely healed -- and we're pretty close now -- they tried to hold me back, didn't want to do anything to have setbacks. Now, they're starting to give me more."
