If Barber left TB... there are always teams who need decent CBs. The question is who needs one NOW and has the salary cap room to get him?
On 4/22, the Steelers only had $326,000 available - so I doubt he'd go there.
There are 4 teams with lots of salary cap room and a good chance at the SB that I see as potential buyers of Barber's services.
Vikings - $13.5 million available
Chiefs - $7.2 million available
Seahawks - $5.1 million available
But if I had to bet on where Barber would end up if he left TB... I'd have to go with the Philadelphia Eagles. They have $10.4 million left to spend. They've already signed Owens and Kearse. They've lost three straight NFC championships. They just lost both starting CBs (Taylor to the Seahawks, Vincent to the Bills).
Our purpose on this planet is to laugh. For in Hell we shall not be able to and in Heaven it would not be proper.
