It must be the offseason because Darrelle Revis is on the market and he has teams falling all over themselves to sign him. After one season in New England culminating in a Super Bowl win, the Patriots didn't pick up the option on his contract which means he's free to sign anywhere he wants. And if the 29-year-old corner changes teams, it will be his fourth in four years.
Revis spent the first six seasons of his career with the Jets which is where he first earned the nickname "Revis Island" and was an All Pro three-straight seasons. His fourth came last year. He has also been to the Pro Bowl in every single complete season he's played except for his rookie year.
That being said, the Raiders appear to be a longshot to actually land Revis. Returning to the Patriots has to be an enticing option with the possibility of making another Super Bowl run.
Also, Revis always expensive. The Raiders in particular would have to really put some crazy money on the table for him -- estimated at around 25 million per season -- and based on how free agency has gone so far, they appear reluctant to shell out that kind of money. As well they probably should be.
When Revis was a free agent last offseason and the Raiders had a similarly substantial amount of cap space, they made a run at him then too. But Revis wanted to have a shot at a Super Bowl. He got that Super Bowl in New England. And he got paid too. We'll see how that goes this time around.
