I think the easiest way to go about this would be to eliminate all roster spots which are completely locked up, then see what we still have to work with. When listing the other candidates, my personal choices will be bolded.
2 QBs
Peyton Manning. Lock.
Tom Brady. Lock.
4 RBs
Tomlinson. Lock.
Alexander, Holmes, Portis, James, Barber, Westbrook, Peterson- pick 3.
4 WRs
Marvin Harrison. Lock.
Randy Moss. 98 TDs and counting this decade. Oakland or not, still a lock.
Terrell Owens. Philly fans might not like him, but his numbers can't be ignored. Lock.
Holt, Johnson, Smiff, Fitz, Wayne- pick 1.
2 TEs
Gonzalez. Lock.
Gates. Lock.
4 OTs
Orlando Pace. Lock.
Walter Jones. Lock.
John Ogden. Lock.
Roaf, Joe Thomas, Willie Anderson, a couple of other darkhorses- pick 1.
4 OGs
Larry Allen. Lock.
Will Shields. Lock.
Alan Faneca. Lock
Steve Hutchinson. Lock.
2 OCs
Kruetz, Mawae, Birk, Nalen- pick 2.
Lots of people listing Mawae here, but I don't think so. Birk already has one more pro bowl despite completely missing a season this decade, and Birk is still playing at a high enough level to put that even further out of Mawae's reach.
4 DEs
Michael Strahan. Sack record, DPoY award, Lock.
Jason Taylor. DPoY, Lock.
Peppers, Freeney, Mario Williams, Simeon Rice- pick 2.
4 DTs
La'Roi Glover
Sapp, Seymour, Williams, Williams, Williams, Henderson, Stroud, etc, etc, etc- pick 3.
This is, in my opinion, by far the biggest cluster-you-know-what on the team. I could easily list 10 guys who I would not be surprised to see get the award, and all 10 would be deserving. And yes, I totally copped out by highlighting "Williams" without specifying which of the triplets it is.
6 LBs
Ray Lewis. Lock.
Derrick Brooks. Lock.
Brian Urlacher. Lock.
Zach Thomas, DeMeco Ryans, Patrick Willis, DeMarcus Ware, Shawn Merriman, Lofa Tatupu, Al Wilson, Keith Bulluck- pick 3
I didn't even list Seau because he was a '90s guy. During the '00s, he's been a good LB, but not one of the best of the decade.
4 CBs
Champ Bailey. Lock.
Law, Woodson, McAllister, Barber, Samuel, Asomugha- pick 3
4 Ss
Brian Dawkins. Lock.
Sanders, Reed, Polamalu, Harrison, Lynch- pick 3
I know a lot of people don't like Lynch, but in 8 years this decade he has 7 pro bowls. He also has an All Pro, a SB ring, and was a captain on one of the best defenses of all time. I have a hard time envisioning him NOT getting the nod.
2 PKs
Adam Vinatieri. Lock.
Jason Elam. Lock.
If I recall correctly, these two guys lead the league in points scored *AND* in game-winners so far this decade.
2 Ps
I have no clue. Seriously, no clue.
2 KRs
2 PRs
I don't know how the HoF committee is going to break it down, but Hester and Hall *WILL* make the all-decade team in one place or another.
2 Coaches
Belichick. Lock.
Dungy, Cowher- pick 1
