Posting even though I'm not a huge fan of actually watching basketball just for the sake of watching basketball. Stopped doing that after the Jordan era. I am always in favor of Sports Talk, however.
Going to just let your breakdowns speak for those that are also on my list, because I'm lazy. Another note. While you said starting five to my personal team, this is more best-players oriented. If I were building a team to win as best as possible, I think I'd make some changes. And if I were building a team to win and play a style I like, it'd be different still. Jut noting.
SF: Larry Bird.
PF: Karl Malone. This was the hardest for me, just because I don't really have a strong opinion at PF. But the main competitor in many people's minds, Tim Duncan, came along mostly after I'd become less a fan of watching it, so I can't really say much for him.
C: Wilt Chamberlain. Every time I hear serious sports people say something like, "Before Lebron James, the NBA had never seen a guy that was as much head-and-shoulders physically better than everyone else on the court," I scoff. Chamberlain could throw people like rag-dolls, as he did Meadowlark Lemon in a Globetrotter skit. He ran a 10.9 100-yard in high school, and even before high school he ran a 40.9 440. Oh, and in high school he won the Big 8 Conference high jumping competition three years out of, well, three years, and triple jumped more than 50 feet. Do you know that you can't, in basketball, dunk a foul shot? The reason you can't, from a rules perspective at least, is because Wilt Chamberlain could, and the NBA outlawed it to keep him from just doing that every time. Which would have pretty much erased the one weak spot in his game. The widening of the lane, offensive goaltending, and various other rules. He led the league in assists one year, and twice finished with 7.6 or more APG in an era when they were much harder to come by. While blocked shots weren't recorded in his days, he was well-known for them, and once dislocated someone's shoulder with a block. He often led the fast break, especially earlier on, but even did so against Kareem's Bucks in the '72 semi-finals in his mid 30's, several years after recovering from a knee injury that could have ended his career. He never fouled out in a game despite his shot-blocking and high minutes, and later in his career was known for his defense. One year he played more than 48 minutes a game. Oh, yes. Can't forget 100 points in a game, 50 for a season, and 65+ points 15 times to Everyone Else's 7. There's always that. Suffice to say, Wilt Chamberlain was a 7-1 guy who could block, rebound, pass, finesse shot or dunk, block, play defense, run up and down the court, and if they hadn't changed the rules to stop it, he could have been a yearly 100% FT shooter.
Sorry if this got long, I've just always thought Wilt doesn't get enough respect.
PG: Oscar Robertson. The 181 career triple-doubles. The only triple-double ever averaged over a year. The triple-double he averaged over his first five years, during which he also averaged 30.3 points. The first player to average more than 10 assists per game in a season. And all of these done in a time before the three-point line (Which has more to do with points than his triple-doubles) and before, as with Wilt, the criteria for assists was relaxed. He's still in sixth in career assists despite this, and with Kidd and Nash past him, nobody's going to bump him down a spot any time soon. His 181 triple-doubles are first by 43 above Magic, and the only player with anything even remotely resembling a chance at it is LeBron, and he really doesn't have a chance. It's just everybody else has Even Less Chance.
SG: Michael Jordan.
I don't really do teams, they're even harder for me than players. It's even more unquantifiable. But.
I'll agree with your Bulls and Celtics, but substitute in Russell's Celtics for Magic's Lakers.
I can't decide on the year. I'm not even going to seriously try. Havlicek is an all-time great, but started just as the bulk of the other players were retiring or aging, although many of them played good-great right up until the end. Certainly, you could pick most years from their championship years and get a team laden with greatness.
Take 57-58, Russell's second year, for instance. When they had 8 total players who are in the HoF. Two, certainly, (Arnie Risen and Andy Phillips) were in their last year and playing backup minutes. They had 11 players. Of the three that didn't go to the HoF, Jim Loscutoff, was a solid player who put up a double-double (certainly easier to get back then, but still) the one year he got more than 25 MPG. Another, Jack Nichols, had a double-double several years previous, and seems to have been a solid bench option, even if it was his last year.
Or you could just go 62-63, after they got Havlicek to add on to a team that had also added K.C. Jones, but still had the bulk of their early guys playing well. Or you could go later. Or you could just throw a dart, land on any year, and be satisfied.
