Discussion Questions:
1. Injuries: None.
2. This is a battle of bigs. Both teams ran with two-center lineups for much of their games (Boerwinkle and Thurmond for the Bulls, Webster and rookie Jack Sikma for the Sonics). Both teams played tough defense and neither team had a strong offense. Does this matchup favor one more than another?
3. Normally you can dismiss the Bulls of the early 70s by saying that they were always a playoff disappointment. But they really weren’t in ‘75. They won their division (if not by a lot), stomped the Kings and fell in seven games to the eventual champion Warriors. Not dominant . . . but not embarrassing either. The Sonics, on the other hand, had quite a run. They beat the Lakers, beat the Walton-less Blazers and finally defeated the Nuggets to advance to the Finals. None of these teams were terribly strong, and none of the victories were terribly dominant. But the Sonics won, and that counts for something. And then they were whipped by the ‘78 Bullets. So this isn’t a convenient situation where one team folded in the playoffs and one team was great; both teams played pretty well in the playoffs and got reasonably far. The Sonics were probably the better playoff team, but the Bulls were probably the better regular season team. Then again, the Sonics’ PSRS is getting a solid bump from beating the Blazers without Walton, which probably shouldn’t happen.
4. I know that the Bulls have strong defensive guards, but Gus Williams and Dennis Johnson were pretty resilient playoff scorers.
I’m going to put this up for 48 hours, unless I need to keep it open for a tie-breaker.
Post with who you would pick to win this series, ideally with the number of games. And if you have any insight into these players or matchups beyond what is above please don't hesitate to post; the goal (as always) is for us all to walk away with more knowledge than we started with. Lord knows I don't know a ton about these teams
