The questions you should be asking is 1) How confident are you that you can resign Revis? 2) Is his asking price worth the cap hit in the future? I mean he may be a HOF player but he is a CB not a QB or HOF pass rusher? Can you keep him and realistically keep a quality Team intact? and 3)Are you willing to risk losing Revis for a supplemental 2nd or 3rd round pick?
With the trade we shore up RT and add 2 #1 picks plus 2 additional picks to build for the near future. Keep in mind alot of money is going to come off the cap next year when Bart Scott, Dustin Keller, Shonn Greene, Mike Devito, Calvin Pace, Brandon Moore and Bryan Thomas are all UFAs. I mean most will not be resigned.
