Did not read it that way at all to be honest.
There are many issues raised about the Sosnick firm including the fact that Sosnick appears not to spend too much time on the basic agreement between players and owners, has had a number of personal issues in the past, has not had an arbitration, etc.
I don't think there is any doubt you are left liking the guy as opposed to Boros but I also think it is good reading because it lets you into places you don't normally see.
Since I happen to be in the legal profession, the book raised lots of questions for me. On the Boras side, it criticizes and it also compliments. Thought it did a lot more criticism of Moorad without too many good things to say of his approach except he got results.
Would Moorad or Boras have been more interesting? Absolutely. Are they going to open that door. Absolutely not.
I think someone facing the choice of hiring an advisor or not or whether they need an agent or not should read the book and leave out whether it is PR for Sosnick.
