What's left to do in the AFC West?

With Peyton Manning heading to Denver, we got our big score in the AFC West for the free-agency season. Regardless of the Manning addition, it has been a busy week of movements in the division. Let’s look at some of the remaining stories left in the division as free agency slows down:

Tebow’s future: Denver is expected to try to trade Tim Tebow. ESPN’s Chris Mortensen has said he thinks Tebow will be released if he is not traded. I think Denver wants a fast rotation, but there may not necessarily be fast clarity.

Manning’s friends: There have already been reports that Denver could sign former Colts center Jeff Saturday and receiver Brandon Stokley. Tight ends Dallas Clark and/or Jacob Tamme and running back Joseph Addai could also be on the list.

Michael Bush: The Oakland running back has visited Chicago and Cincinnati and is set to go to Seattle. His market has been slow, but circumstances may prevent his return to Oakland.

Chargers backup running back: The Chargers are looking at several players, including Kansas City’s Jackie Battle, as a replacement for key backup Mike Tolbert, who signed with Carolina.

Denver’s defense: Denver still has to improve the defense. It has signed Cleveland safety Mike Adams, but it needs more. Defensive tackle Brodrick Bunkley, who has visited New Orleans, remains a priority. Denver has also been linked to Baltimore linebacker Jameel McClain, Tampa Bay linebacker Geno Hayes and Seattle cornerback Marcus Trufant.
