I think a cap would actually help the more recent seasons - if you look at the top 100 salaries they almost all pre-date 2010. I'm going to leave it as is, I am pretty sure it will fill and I like the single-season concept. We will be putting the seasons into divisions by year, so the more recent teams will have to battle it out amongst themselves to get to the playoffs, and once there anything can happen!
PS I think my 89-90 team is going to dominate the soft millennials in today's NBA....
