ALAMEDA, Calif. -- While punter Marquette King said there might be a bit of a "revenge factor" in play when his new team, the Denver Broncos, faces his old team, the Oakland Raiders, don't expect Jon Gruden & Co. to sweat it much.

Not when the Raiders, in the wake of releasing King last week, maintained their ways of being the busiest team in the NFL since the start of the new league year on March 14. And King's "revenge factor" won't register when the Raiders begin their offseason training program Monday at their facility -- the event Gruden has been waiting for since he was hired in early January.

Consider: since then, Oakland has signed 19 new players, re-signed four of their own unrestricted free agents, tendered all five of their exclusive rights free agents, cut three players and traded away two more. And that's not counting the moves the Raiders made before the league year began. You truly need a tracker to keep track of all the comings and goings in Oakland this spring.
