I agree with Beerlover in regards to free agency, except that I would go hard after Asante Samuel. Just my preference.
I believe that the CB position is worth spending a boat load of cash on. There are other ways to increase our available cap space. For instance, if Payne, DD/DW, Greenwood, & Wiegert were cut after June 1st, or would be willing to do what McKinney did & take a pay cut, we could trim anywhere from $6-9.3 million off of this year's cap. According to HPF's site, we currently have about $13.3 million in available cap space. By adding the additional space, we'd have somewhere in the neighborhood of $19-22.5 million to spend on free agents & draft picks.
Now, before someone comes in here & points out the obvious fact that we'll have to replace them on the roster, let me point out a couple of things first.
First off, if they accept pay cuts, the problem is solved. Assuming they don't & we have to cut them, I believe Payne has already been replaced by Maddox, & my draft proposal at the end of this post will address the 2nd DT position. DD/DW is damaged goods & probably always will be. His replacement will be taken during the draft. Wiegert is old & will probably accept a pay cut, but if he doesn't, Winston showed me enough to make me believe he's ready to take Wiegert's job. We'll address depth in the draft. Greenwood is the only one that I don't want to lose, but his performance doesn't justify his salary. This'll be the tough decision.
One other option, while I'm not a proponent for trading Carr (I truely believe he'll be a good QB for us in the future), cutting him, or trading him could net us an additional $3.25-5.25 million in cap space. If we're willing to go with Sage as our starter, while grooming a rookie (Kolb?), I could live with it. After all, I'm a Texan fan, not a player fan. By doing these things, we could give ourselves ~$22.25-27.75 million in total cap space. Or, at least, that's what I believe, & that would get us an elite CB like Samuel or Clements.
Now, it's my opinion, that the top 10-15 picks will be shaped by what Oakland does with the 1st pick. Will they take Russell, or Johnson? If they take Russell, I doubt we'll get a shot at AP (Cleveland).
So, back to David Carr. If we were to contact Oakland about a trade for Carr, that might encourage them to take Johnson with the #1 pick, thus giving Al Davis his starting QB & a stud WR. Then, one of Russell, or Quinn would be on the board when Cleveland picks. Hopefully, they'd choose a QB over AP.
As for the trade, I'd offer Carr/4th round pick for Oakland's 3rd/5th round picks. I'd even consider trading Carr for their 4th round pick this year & a 3rd next year, that could escalate based upon his performance. For my draft proposal, I'm going to assume (wishful thinking) that they accept the first proposal.
Let me make this perfectly clear, I like AP & would love to have him on our team, but if AP falls to us at #8, I'm going to call Green Bay & see if they'd like a shot at him. I believe that we've got to finish the DL/OL's before we can truely start adding the elite skill players. Without a strong foundation (OL/DL) first, we'll be back in the basement faster than we can shake a stick.
Anyway, back to the trade. I'd like to get Green Bay's 1st & 2nd round picks, but they've got a lot of holes to plug as well. So, I'd be willing to accept their 1st & 3rd this year, along with their 2nd next year. Assuming all of this happens the way I'm dreaming it would

, here's how I would draft in the upcoming draft.
1) (#16 from Green Bay) Amobi Okoye (DT) 2nd choice: Adam Carriker (DE)
2) Ben Grubbs (OG) 2nd choice: Ryan Kalil (C)
3a) (from Oakland) Tony Ugoh (OT) 2nd choice: Kevin Kolb (QB)
3b) Kevin Kolb (QB) 2nd choice: Ryan Harris (OT) 3rd choice: Samson Satele (C/OG)
3c) (from Green Bay) Dwayne Wright (RB) 2nd choice: Ken Darby 3rd choice: John Wendling (FS)
4) (traded to Oakland) no pick
5a) (from Oakland) John Wendling (FS) 2nd choice: Josh Wilson (CB) 3rd choice: C.J.Gaddis (CB)
5b) Stephen Nicholas (OLB) 2nd choice: Juwan Simpson (OLB) 3rd choice: Desmond Bishop (ILB)
6) Keith Jackson (DT) 2nd choice: Jacob Ford (DE) 3rd choice: Justin Hickman (DE)
7) Jacoby Jones (WR) 2nd choice: Aaron Fairooz (WR) 3rd choice: Paul Thompson (WR/QB)
Ahh, if only fantasy were real. Right or wrong, that's my story & I'm sticking to it.
