Please don't go crazy. I don't want Sexy Rexy under center any more than anyone else does. I also don't think we're player rich enough to throw around a bunch of draft picks to trade up or to take a shot on another guy we're not sure of.
If, between the upcoming draft and free agency, we land a legit shackles corner, a jump up and grab it receiver, a new tackle and a pair of guards (rich FA year for guards), and a solution at strong safety, could you take one more year of Rex, knowing that we'd THEN push our chips in to grab Matt Barkley or someone else who proves himself?
Never mind the "does Shanny need to win next year to keep his job" thought process. I'm not talking about what's likely, I'm talking about what makes sense. You're the owner of the team, and you're not trying to pull off one playoff run; you're trying to build a perennial contender.
