Second, picking a set of rules on defense to play under is not going to happen same as I am not going to decide if the teams are going to play with or without a three point line, with two refs or three, or any other rules changes that have occurred since 1959.
While I hear what you're saying, and their are practical difficulties. At the same time, I do think it's odd not to have any standards, yet have panelists judge teams based upon their own criteria. Playing a game, but not having notice of the rules, just is counter-intuitive to me.
That being the case, out of fairness I'm going to let the team owners know what my personal judging criteria will be. If Edgar and Dons want to share there's, good for them; I think it would be more fair to the contestants.
So, for me,
I'll be assuming these teams are playing under current rules. While I personally prefer a 1980s style of game, I think the current rules are the ones our GMs are most familiar with. That means there's a three point line, there's no hand-checking, the width of the lane is its current width, the game is less physical overall, etc.
Everything else, I'll keep to myself (i.e., my views on how 1960s players would adjust to the modern age, whether "one year wonders" count the same as all-time greats, how chemistry factors in, the effect of injuries, etc.) I'll share my views on all of that at the end of the game. However, regarding the basic rules of basketball teams will be playing, I figured it was fair to let folks know where I was coming from, and how I'd be judging.
