I still think there is a great situation to send Youkilis to Chicago for Thornton for the following reasons (for all discussion purposes, contracts will not be prorated):
1. Youk + $3mm + a mid-ceiling prospect to Chicago. Youkilis has a $11.5mm contract this year. Eat $3mm of his salary, and it's down to $8.5mm.
2. Thornton is under contract for two years at $5.5mm each year, at a total of $11mm.
3. By taking on Youk's $8.5mm this year, and getting rid of Thornton's $5.5mm next year, they are essentially riding themselves of $2.5mm, and in the process, are getting out of the deal 1 year sooner.
4. The White Sox are a rebuilding team. They are a team who would love to free up money to spend on the draft, international FA, etc. If they can relieve themselves of Thornton's salary next year, that's one step closer to rebuilding their franchise into a young organization.
So, in essence, the White Sox aren't really trading "for Youkilis". What's essentially happening is that the White Sox are getting a young prospect, and are taking a discount on Thornton's contract and getting 3/4 of a year of Youkilis. I can absolutely see that happening, and I can see the back of this bullpen being helped out tremendously by a swing and miss guy like Thornton.
