Lol, you discredited your own premise by admitting that percentages are the same and they are just as efficient from way deep. That should be the end of the conversation, but you'll continue to go all in. So, I'll add that you forgot all the other aspects of what happens when the zone is extended. You've yet to or refuse to talk about that part. I wonder why. You might not believe this, but every action by an offense, tends to force a reaction by the defense.
Your logic...'Now listen team, the zone doesn't need to extend past a foot deeper than the line, I want you to leave them wide open if any deeper than that, as they are just as likely to make the shot, the numbers don't lie'
Do you have any #'s for percentage of wide open 3's made and percentage of shots made when guarded vs our zone?
Can you breakdown the numbers for me of how many different players on a team would hit a 3 back then, as compared to now, Mr Numbers? Now do the numbers for multiple 3's made by multiple players from way back when compared to now.
Let me guess...you don't have those stats.
