Who is ESPN the Mag's NFL Player X?

First of all if you are a subscriber of ESPN the Magazine I hope you enjoy reading the articles by "Player X".  He is a player in the NFL and has written 10 different articles for the Mag.  I know not everyone is an ESPN Insider so as I'm rereading I'll highlight some of the hints as to who exactly Player X is.
Before I get into it, let me first say I really enjoy the articles so I'm not trying to "out" him or anything, this is just a fun little exercise to see if this anonymous author gave away a few too many hints.
So think of the stars on different teams and as I eliminate teams, we'll see if we can figure out which star he is.

Meet Player X:
- not Ben Roethlisberger.

Vick deserves right to play:
-he believe's Vick deserved a shot to play, does that eliminate anyone?

NFL rookie hazing has purpose:
-he likes rookie hazing and says it has a purpose, so he's not an Eagle? Any other teams?

Currency of pain:
-he's not Carson Palmer
-he's been around long enough to remember the days when it was easier for players to get painkillers.
-he's not Brett Favre
-he's not Hines Ward
-he's been injured. wait, that doesn't eliminate anyone.

Team chemistry overrated:
-he's not Chad OchoCinco
-he's not Terrell Owens
-he played in college

How to spot a contender:
-he's not on the Colts or Texans
-he's not on the Ravens or Steelers, but watches tape of them
-he's not Troy Polamalu or James Harrison
-he's not on the Saints
-"My team lost a division game this year (so now you know I'm not on the Colts or Saints)"
-he has made the playoffs (not on the Texans).

It's mailbag time:
-he's not on the Raiders
-"I know I'm better than a couple of guys at my position who are paid more than me". so he's not the highest paid at his position
-not Chad Pennington or Chad Henne. but maybe he played with them since he think they are funny. also says Ochocinoc and Brett Favre are funny too.
-He's not Donovan McNabb, but that's fine since I already eliminated the Eagles.

Tiger shoulda known:
-he's not Tom Brady
-he has endorsement contracts, doesn't eliminate much
-he's not Peyton Manning

10 NFL playoff lessons:
-he's been far in the playoffs (whatever far is we can say that means his team made it to the final 8)
-he's not Kurt Warner
-he's an old enough veteran to call out/joke with rookies (probably doesn't mean much)


Gun culture changing in NFL:
-he has bought a gun

So, basically I skipped a lot of maybe hints and just went for what seemed like definite stuff about Player X and we still don't much about who it is.  Teams I eliminated: Eagles, Raiders, Ravens, Steelers, Texans, Colts, Saints.  That still leaves a lot of options, hopefully we get some more hints in a few more articles from Player X.  If you have any hints, tips, or opinions add them in the comments.
