What are your thoughts on extending the length of the season so that we have fewer (possibly no) back-to-back games? Perhaps you eliminate the preseason, start the season in early October and end it by early/mid-July with the draft now occurring in late July and free agency in August. That would mean only two and half months of no basketball (really only one month since we would have the draft and free agency to keep us busy at the end of July and August).
Another somewhat related idea: Trim the playoffs to 8 teams and have the lottery consist of 22 teams, so even a good team has a chance of getting a great prospect (perhaps you even provide greater odds than currently so we can further discourage tanking). I think we've only had two or three teams seeded lower than four make it to the Finals (the only winner that comes to mind is the '95 Rockets, who were a fifth seed that benefited from Shaq/Penny choking), so why not just have the four best seeds in each conference duke it out? When you get unusual circumstances such as four teams tied at seeds 3-6, settle the third and fourth seeds with a win-or-go-home 83rd game where the three hosts the six and the four hosts the five.
What are your thoughts?
