Difference is...the Cards signed Carpenter on the cheap, with the hope that once he got healthy he would reward them for their patience; which he has. Meche, IMO, will not be cheap to sign. Quite frankly, he won't be worth the bills he might get. Our version of "could be great for cheap" is Miller. If he re-signs again, which I don't know why he wouldn't. The Cubs paid him for a year to rehab, the least he could do is sign for another year with us.
