The Celtics playing would actually work out considering that we have a team full of American players. I think what would be most important for the USA team (whoever is composed of) is a coach committed to defense. Like our Cs have proven, defense wins championship. Team USA would need a coach (or assistant coach) that would be able to figure out the international system and design a plan to stop that, then have the players committed to playing that kind of defense. Offensively, nobody can stop the US, me thinks.
For that reason, I think the Celtics would absolutely have all the goods to beat any international team if, and only, coach Tibby would be able to figure out how to play their D. I think his more than capable, but then again, that could just be a whole new ballpark for him. Good question though.
PS. About partying, I know I sound like a grandpa but remember to set your priorities straight. Go out, have fun, but never allow it to effect your work. If it starts getting to be too much, just focus on relieving all that stress during the weekend. Shift ur focus to work on weekdays, and party on weekends.
