You had it right up to the point where you equated the MLS with Boras. If the sox dont get this done, the egg will be on their face much more than what it would be on the agent. The agent is there to get the best deal for the player, the right value. In today's market, Matsuzaka, as a FA would make 16-20 mil a season. At the same time, seeing as Matsuzaka has had his fate controlled since he was in diapers, having the sox have 6 yrs of control over him is unfair and should be something that Boras exclusively seeks unless they pay him handsomely for his 6 seasons. The sox showed their hand. You dont bid half a hundred mil on a guy then be afraid to offer him a ton of money. If the sox were not prepared to offer the big contract then someone else would have.
Overall, who would look worse?
The agent trying to get a player favorable deal.
Or the team that bid a major league record 51.1mil who is trying to save a buck now and have a company friendly contract.
Sorry, but the sox showed their hand with the 51.1 and if they arent willing to pony up the dough after spending 51 mil just to talk to Matsuzaka, then the egg is on them. It may hurt Boras, it may not. But if the sox dont close this, they will be significantly affected in the market that they so wanted to open up, and not in a good way.
