Bird and Magic had very unique relationship. Just watch "Magic & Bird: A Courtship of Rivals." It's an amazing story. Anyway, here, this is a tough one, LOL. Absent any friendship, they are all hired guns. They have to be competitive, vie for business, compete for business, and of course compete on the track. But, they also have to see each other and co-exist with each other in the room. So, some are friends, some are not, LOL. I guess to some extent and in some ways, it's similar to any other similar business environment. There are some very strong friendships there, but they are still competitors. Some socialize, travel together, and so on.
Yes, Doug Brown and Bill Gale were fierce competitors. They did go to war a few times, LOL. But, they also respected each other's talent, ability, etc. There were times they didn't like each other, but with those two that was to be expected, LOL. There was a time when Bill was the go-to driver for Bob McIntosh, and Doug was go-to for Stew Firlotte. Bob had a nice 2yo and whatever the circumstances were, Doug got the call. Well, that didn't play out to well, LOL.
