Like you have pointed, that was a business decision. Perk might not have wanted to play the game, but he allowed his agent to play, of course the outcome didn't please him. I'm sorry for the sadness around the team, but I have nothing against Perk, wish him health and success because he seems like a good honest man.
The most interesting thing, in my opinion, is the example Danny has set, a bit like Bill "Hoodie" Belichick (if you want out, I'll help you). What do you think BBD is thinking about resigning with the team? How much will the Celtics offer him? Well, he wanted to "test the waters" 2 seasons ago and his value around the league wasn't as high as he thought. This summer might be different, but I bet Danny will lowball and invite him to "test the waters" again if he doesn't like the Celtics offer.
Well, I think it depends on what happens with Jeff Green and the health of our centers. If Shaq, JO, and Nenad are healthy, BBD's days playing center are probably over. And if Jeff Green is going to play with the starters, he may take Baby's role at the end of games.
That could lead to a drastic drop in minutes, which could lead to one of two things:
1) BBD's stock drops big time with his numbers and the C's can keep him at a reasonable number.
2) Baby sees the writing on the wall and leaves even if it means going somewhere else for comparable money to what the C's offer.
As for the feeling bad business that others are discussing, I'll say what I said earlier. We get emotionally connected to these players, so it's natural to have sympathy. However, there does need to be an end to it. As I said before, Perk is a professional athlete making millions of dollars, not a starving child in the developing world.
Feel badly for him for a few days, but know that he's going to be just fine.
