This stuff is fun. I'll give it a shot.
First, Wedman and Sichting were nothing to write home about. Wedman was an all star earlier in his career, but he was on the downside of his career by then and Sichting was basically a shooter.
Bird under today's rules does anything he wants to on the court and it doesn't matter who guards him. Smart vs him would be interesting, but Bird takes him into the low post and that's it.
I also think Bird guards Jaylen and does a decent job of keeping him from getting to the basket.
Brogdon vs Sichting and even Ainge is a total mismatch. He'd be a problem.
Also we still don't know the peak of the current team because Rob isn't involved. But I think Parish neutralizes him.
I think it comes down to an in his prime McHale vs Tatum. McHale at that time was a great defender and he could guard the best guy on the other team when needed and do a great job. He'd limit JT's ability to get to the basket and would have help from Parish and probably Walton when he's in. So it comes down to JT's 3 pt shooting.
Also the 86 team has tons of problems with today's style in terms of the ball being moved around the perimeter. The 86 team would score lots of points as well. The current team, at times, struggles to rebound. 86 would pound the offensive boards and get tons of 2nd chance points. They'd also control the defensive boards.
All the games would be like 130 to 128.
I think it's a tossup - though personally I think the 84 team is a better matchup because they had Max who would be able to guard both Tatum and Brown - and also Gerald Henderson who's a better match up vs Brogdon.
