I don't buy that bs. I'll trust the experts in the industry over a clever poster (I mean that as a compliment) who wants to win an argument. And here is my problem with your argument. If the Sox challenge the rule then they are throwing all the other teams under the bus too.
If me you and 3 other guys went out to the tittie bar and left our wives at home, and then get into a fight and only I got arrested and end up in the newspaper, I'm not going to run and tell the world that everyone else was there too just because I got in trouble.
That is exactly how you make enemies, I seriously doubt that John Henry wants to make an enemy of 1/2 the other teams in the league.
Again, the Sox didn't exceed their bonus pool, they didn't exceed 300K on any one player they DID try to circumnavigate that rule by bundling contracts. However they are the only team that is getting in trouble for the latter of those even though it's been widely reported that bundled contracts is common. Reported by respected industry insiders. Reported not just today buy a year ago when teams were entering the second signing period of having to work around such restrictions.
Again I'll take the word of respected industry insiders over choosing not to believe what they reported just because the Sox havent' pushed back against it. And for all we know they may, this is day ONE.
