Matzusaka was a bust but I can't laugh at the sox about it because I read scouting reports on him for about a year prior to his signing, and his stuff appeared to be the kind that would translate well, except for the high change up.
It turned out to be 103M total PLUS this nice list of incentives:
perks: physical therapist, massage therapist, interpreter, 8 first-class round-trip airline tickets per year between Boston & Japan, spring training housing allowance of up to $25,000, Boston housing allowance of up to $75,000, one-time moving allowance of up to $35,000, use of Lincoln Town Car or similar car, Red Sox player ticket package, including 2 field box seats, team employee to assist Japanese media, uniform No. 18
