Javier Arenas traded to Cardinals; Chiefs get fullback Anthony Sherman

Javier Arenas is on his way to Arizona. The Kansas City Chiefs have formally announced the trade involving Arizona Cardinals fullback Anthony Sherman and Chiefs cornerback Javier Arenas. Arenas is headed to Arizona to play for Bruce Arians and the Cardinals while Sherman is coming to Kansas City to play under Andy Reid.

Arenas' agent tells NFL.com: "This is a trade where, based on Kansas City's acquisitions at the cornerback position, we were actively pursuing. With the trade made, we're happy it's to the Arizona Cardinals."

Arenas moving out of town shouldn't be a huge surprise. The Chiefs added Sean Smith and Dunta Robinson in free agency, and drafted Sanders Commings in the fifth round. That's a big investment into the secondary but even before that Arenas wasn't guaranteed of a roster spot.

Sherman was a fifth round pick in 2011. He played fullback at Connecticut (team captain!), appearing in 51 games. Sherman blocked for Beanie Wells' 1,000 yard season in 2011. Arians wasn't big on fullbacks so Sherman was expendable.

What makes this interesting is that the Chiefs just drafted Braden Wilson, a fullback out of Kansas State, in the sixth round. Are they going to compete with each other? Or will they have different roles? Also, why wasn't this trade done before the draft? Not that it matters ... I was just curious when the talks started.

Arenas was a 2010 second round pick. He was a good role player but wasn't outstanding in any one area.
