When Grissom graduated he was a top 100 prospect in baseball. He will be 23 all of next year and comes with 6 years of team control.
It is blatantly obvious that this trade was all about getting Grissom in the door.
Any team, with the financial position to do so would have done the same, including the likes of LA and NY. This was never a salary dump. If it was they would have found a team who would have taken a larger porition of his salary and taken back a much lesser return.
I also don't agree that this is any way handcuffs the Sox (saving only 10 million instead of more). I'm not defending the front office as a whole, but no matter what people want to say they've been pretty consistant with total money spent and what they've said. Sure, they've signed some bad contracts, ignored home grown talent, refused to be serious on the big boys. But they've consistantly spent up to the tax line, and when they've felt they had a chance to win gone above it.
Sales money with or without this trade was off the books at the end of this year. If there was a financial decision to be made that would put them over the cap this year, and they thought they had a legit shot at winning, they would just do it, and they can reset next year.
