If Dominique Rodgers-Cromartie covers the reception area as well as he does the 140-character Twitter space, the Broncos might finally have themselves a decent right cornerback.

The Broncos and Rodgers-Cromartie agreed to terms Wednesday night on a one-year contract worth $5 million, completing a furious day of free-agent activity for the team.

The Broncos also agreed to new contracts with receiver Wes Welker (two years, $12 million), defensive tackle Terrance Knighton (two years, $4.5 million) and linebacker/special teamer Stewart Bradley (one year, $1.2 million) earlier in the day.

Those signings came a day after the Broncos opened the free-agency period Tuesday by agreeing to terms with right guard Louis Vasquez (four years, $23.5 million) and re-signing defensive tackle Kevin Vickerson (two years, $5 million).

Add in the franchise tag applied to left tackle Ryan Clady and re-signing of safety David Bruton to a three-year, $4.5 million contract and the Broncos have allocated close to $66 million worth of contracts in the free-agent period.

Asked if the Broncos were pushing their salary cap limit, Broncos’ front office boss John Elway said, “No, we’re in good shape.”
