Former Jets CB Darrelle Revis is now a Buccaneer, strengthening the Bucs' secondary. Not unlike the Dashon Goldson acquisition, Revis is a risky, high cost choice that will make them better, but that will also cost them dearly.
In this case, $16 million a year, their first pick, and a high pick next year.
This impacts Carolina another way - the 13 pick that's involved in the trade is now the Jets', and it's hard to say what they'll do. They're short on defense, and definitely have a hole at CB now. They have tons of needs - and even with a lame duck Rex Ryan, who knows. You could see them pick a QB. They need a WR. So they're now a total wildcard. They could pick anything, where the Bucs needed an end and the rest of it more or less flowed at Carolina's needs.
