if he is looking to leave , the urge must have hit him recently. it looked to me like TJ in that tweet was lobbying JJ to come to pittsburgh.
if he does have his heart set on leaving, i hope they are smart enough to trade him and get something out of him instead of forcing him to stay for another year.
maybe he heard they were going to cut derek ? or he asked them to sign JJ and they said no. or MAYBE it is a bullshit rumor a cleveland fan started.
