Asked about the future of Houshmandzadeh and Stallworth with the Ravens, coach John Harbaugh said, "The answer is I don't really know. You can't put a percentage basis on it. There are so many things that are up in the air at this time."Houshmandzadeh, 33, caught 30 passes last season, his lowest total since 2003 and a 63 percent drop from his 2009 total. Even though he signed on as the Ravens' No. 3 wide receiver, he often complained about his reduced role on the offense.
