Aren't you the same guy who always says that money shouldn't be an issue, we have it might as well spend it, it's not your money, etc. Granted, all of your points are very valid but still, Andy represents something, and sure he had an off year last year, but look at Mussina, he had a bad 2007 and won 20 games last year. I really think Andy could pitch representable next year and then hang 'em up. He's won a lot of big games for us, and he wants to pitch in the new Yankee Stadium and be a part of that so I say we owe it to him. I'd take it a step further and give him the start at the home opener. Granted, even $10 Mil is a lot but that's already a $6 Mil paycut. If he has a problem with the generous $10 Mil we're offering then I say let him go, fine.
Also, part of my desire to bring Andy back is the presence of another lefty in the rotation. You need lefty pitchers in that ballpark so the lefty hitters don't pull everything off right handers into that short porch.
