I'm contemplating this deal (giving Hamels et al, getting PABST et al) mostly to jumpstart my moribund and depressing offense and reignite my interest in life. And by "contemplating" I mean "it's on the table."
I think I can afford to lose Hamels, especially if Scherzer does something useful in the stretch drive in September. I could care less about Garza; in fact, I only included him because the other dude already offered him in a different iteration so I thought his inclusion here might make other dude more amenable to the deal.
So Morneau and Rios for PABST and Vlad? You moving to Anaheim? Roy E. Disney paying for you to race a boat to Hawaii?
Morneau decided to take a dump in August. Rios decided to take a dump this season. How is his top month output for home runs at 4? Who is he, Michael Bourn? Sorry, I'm frustrated for you. I can only imagine how you feel.
I think it's a risky move, but depending on where your team is, you have to make some risky moves this time of year. You definitely should come out with more offense than what you're putting in. If you're desperate, it's a move worth making.
