Still working, Chiefs make move on offense… Andy Reid widening the path for Jamaal Charles.

The Chiefs trade cornerback Javier Arenas to the Arizona Cardinals in exchange for fullback Anthony Sherman, sources told’s Ian Rapoport on Wednesday.

With Sherman in and Arenas out 45 of the 90 Chiefs are new this season. Remember, John Dorsey wants that solid 43.

“This is a trade where, based on Kansas City’s acquisitions at the cornerback position, we were actively pursuing,” Arenas agent Hadley Engelhard told Rapoport,” Arenas is happy with the deal. “With the trade made, we’re happy it’s to the Arizona Cardinals.”

It’s reported the exchange “made sense” for all. New Cardinals coach Bruce Arians has little need for a fullback in his pass-first system, but Reid will use Sherman in his West Coast Offense.

The Chiefs also drafted K-State FB Braden Wilson in the 6th Round (204th Overall). Second-year player Nate Eachus is also on the roster, but small for a FB.

Reid’s wanting a lead blocker for Charles, get Charles into open-space, but experts say it’s “a skill set still in progress” for Sherman. ProFootballFocus graded him 19th out of 25 fullbacks as a road grader in 2012.

Reid said there would be competition; honestly I knew the writing was on the wall for Arenas. He didn’t make much sense to me, another Scott Pioli pick down.

Good day, Chiefs fans!
