If I had to manage the payroll and could get a quality #4 for $2.5 or less I think I'd go for it. What I don't know is whether Miller will be traded, healthy or ? What I don't know is whether Roger will be back? What I don't know is whether Backe is a fluke or the real deal. What I don't know is the prognosis on CH returning to preinjury velocity and form. With a healthy Miller + Roger + 'real deal' Backe + AP then I doubt I'd pay more than $1 mil for WW while spending $$$ to shore up other holes instead.
http://www.chron.com/cs/CDA/ssistory.mpl/front/2924934 Per Houston Chronicle: Discussed making an offer to Houston native Woody Williams. He's a free agent after winning 11 games for the Cardinals last season. He's 38 years old, but keep himself in top physical shape. He's one of the real good guys in the game.
