This would be a good move. I don't trust our veteran safeties to come up with clutch plays to close out games. Woodson and Roy Williams come to mind as the last ones to do so.
Good signing for Tampa Bay. I loved TJ Ward with the Broncos. He was the true tone setter for the defense. He has some major limitations though. He needs to be a box safety that is more in for run support than coverage. Can definitely be a huge liability in coverage. The other issue is injuries. They have really piled up over the past 2 seasons and started out this year with a hamstring injury.
