John Harbaugh is "optimistic and hopeful" that wide receiver Derrick Mason will come out of retirement and rejoin the team during training camp. Mason had a strong 2008 season, but said he was "ready to see what else life has to offer." After speaking with Mason on the phone Tuesday night, Harbaugh maintained hope that Mason would have a change of heart soon after the start of training camp next week. "I think it's real honorable what he's doing in the sense that it would be easy for a guy to just come in and go through the motions. Derrick does not want to go through the motions," Harbaugh said Wednesday. "He wants to make sure he's in the right frame of mind to compete at the level he's competed at his whole career, which is a warrior-type level. "He's ready physically. He's in good shape and he's healthy. He just wants to decide if he's mentally ready," Harbaugh said. "It's really open right now. I'm optimistic and hopeful that he'll be there, but if he's not there, we'll be support and respect his decision either way."
