I agree on Kinsler. JV would have to be VERY consistent up to the trade deadline in order for anybody to risk that contract. If you could move Sanchez, it would be a salary dump move and not net any top prospects because of his injury history and declining numbers. I don't see any team picking up Miggy's contract. Declining numbers, increasing injuries, increasing weight and on the first year of an 8 year contract.
Now, if Zimmerman can pitch lights out for the first half, he could get you a good haul. Most people say that the Tigers signed him to a reasonable contract. An "ace" with a reasonable contract...someone might bite.
You do all that and suddenly we aren't winning for years. Trade Anibal but Zimmerman should stay just based on "reasonable contract." Same with Kinsler. No way you find a 2B better than him.. not in our farm system.
