nfl.com says that, according to the selection guidelines, only a player's performance during the decade can be taken into consideration.
Outside Linebackers 2000-2009
AP first team All-Pro selections
Derrick Brooks 4
DeMarcus Ware 3
(several) 1
Common sense says Brooks and Ware would be the two first-team OLB's on an all-decade team that necessarily included two OLB's. Historically, these teams have included two OLB's, but it's hard to tell how the voters looked at it this year, because they were only asked to choose six linebackers (meaning three first-team LB's). There was no distinction made about inside or outside LB.
King and Gosselin are both members of the selection committee, and they've already published their teams. Both included two OLB's on their team, and in both cases their selections were laughable.
Gosselin: Brooks and Keith Brooking
King: Brooks and Mike Vrabel
If their selections are an indicator of what the committee did as a whole, then the good news is that they did indeed feel they had to include two OUTSIDE backers. The bad news of course would be that there might not have been enough of them who even considered Ware at all, because of the timing factor, and someone like a Porter could make it ahead of him.
It will be interesting.
