I think you also have to take into account the lefty+ Fenway factor, swapping Lowell for LaRoche is not only a semi-lateral move, but a waste of money.
You also need to calculate the fact that Lowell displayed increase mobility towards the end of the year, the difference in defense might not be so drastic next year.
But "eating that money" decreases financial flexibility on the accounts of a lateral move. It makes no sense.
The Mariners can fill the couple holes they have without acquiring a hitter ill-suited to play in their stadium. Because remember, the deal has to make sense for the other team as well, because the other 29 teams in MLB are not feeding tubes for the Sox k?
