I've mentioned it a few times in other threads, but I think this is a good year to punt on the season and trade in expiring contracts to the massive number of contending teams. The two of the last three years, the FO has tried to hold on to a hopeless season, and wasted trade chips and avoided earning big windfalls. I haven't done the math but I think trading Beckett and Youkilis could get them under the luxury cap.
This is Beckett's last good year. His fastball speed is declining every year, and he's reaching the point in the contract where he'll stop being worth the money. He's good enough that a desperate contender would be willing to pay for the full contract and give up one, maybe two elite pitching prospects in return for him.
This is Youkilis's last year in a Red Sox uniform. Why not see what they can get in return for him?
Dump Salty. He's got a .860 OPS with a .300 OBP and some have suggested he may get an All-star nod. Someone will want him, but he's such a liability on the defensive end.
