Beside the Broncos, the Raiders are the most actively interested. Woodson has accepted an invitation by the Oakland Raiders to visit the team this Tuesday.
The draw to Oakland might not be strictly financial for Woodson; should he sign with the Broncos' AFC West rival, he would be reunited him with his original NFL team. The Raiders drafted Woodson in the first round (4th overall pick) of the 1998 draft; Woodson spent eight years in Oakland.
Meanwhile, the Broncos' offer is standing, and was reportedly for more than the veteran minimum. Other teams have "balked" at offering Woodson more than the veteran minimum, according to Rapoport, but this visit with Oakland is a sign that may change.
Credit Woodson's agent for doing his job: using the media to drum up interest around the league, legitimate or not, and likely upping the price tag for his future Hall of Fame client in the twilight of his career. The Broncos now have serious competition in the Charles Woodson sweepstakes.
