Goose was a little over the top for sure. He's an old man that once played baseball and no one has put a microphone in front of him for a long time. So, he decided to make what could be his last public comments something to remember him by. I think he made himself look pretty bad and the players he spoke about handled it with a whole lot more class than he did.
As for Morgan and the whole "money ball" thing, I wouldn't assume he had any more tact. Certainly when he was broadcasting he kept his language in check but some of his comments outside the broadcasting booth had every bit as much vitriol as what Gossage said. I posted a link in the "off season" thread to an article entitled something like "my encounter with an angry Joe Morgan". You should read that.
Incidentally, I just re-read "Money Ball" for the first time in 10 years. in the latest version, Lewis adds some additional information about the reaction to the book that were not included in the original release (because, how could they be). Joe Morgan had a lot to say about the whole thing and none of it was pleasant. But, that wasn't close to the low water mark. The low water mark was after the Blue Jays hired one of Bean's assistance, J.P. Ricciardi, to be their new GM and try to turn that franchise around and make it a success. A couple of reporters up in Toronto argued that the money ball philosophy was really disguised racism because, and I swear I'm not making this up, it reduced the amount of minorities on the team. See, Toronto is a diverse city and they felt they should have a team that reflects their diversity. They made this ludicrous argument despite the fact that the Toronto Blue Jays - which I'm sure you'll agree represented an incredibly small sample size as compared to the city - actually exceeded the diversity ratios of the city itself. So, after that was thrown in their face, they then made the argument that - and, again, I swear I'm not making this nonsense up - that it was racist because Jackie Robinson wouldn't have been brought up with the Dodgers if Branch Ricky had followed a money ball approach and the color barrier would not have been broken. This is ridiculous on 2 fronts. First, Jackie Robinson was a great player by money ball logic as well. Second, if the Dodgers had a different view on player and how to value their talents back in the late 1940s, then they would have found a black player who fit that model. Ricky's goal was not to break the Jackie Robinson barrier, it was to break the color barrier. He had the idea first, and the player 2nd.
The problem with Gossage and Morgan and people like them is they believe they are part of some special fraternity and people who were not part of it can't understand it or have opinions on it and, if they do, those opinions must be wrong because they were not part of the fraternity. There is no doubt that having the physical ability to play major league baseball makes you part of a very small fraternity. But, the idea that bestows upon you some hidden wisdom that no one who didn't play the game at that level can possibly fathom is demonstrably bullshit. The A's, and now other teams, have proven that. The Royals just went to back-to-back World Series, and won a championship, with a small pay roll using the exact logic promoted by Billy Bean and the A's. And, this past year they beat another team that was using money ball logic in the Mets. The problem that these teams have now is that more and more teams are embracing this and getting the kind of hidden bargains Bean used to get is proving to be a lot more difficult. For him, I suspect the worst part of that book is not the criticism - I doubt he cares - but that it got too many other front offices thinking the way he thinks.
As for the comments about the bat flips, Gossage may want to go back and watch some games from his era. His belief there was no showboating back then is also wrong. It was just different.
