The value of the 1 seed will be greater now than it was for the first 30 of those 34 years. For 30 of those years, the 2 seed also got a bye, hence the automatic win and injury avoidance too. The 2 seed no longer has that, so over time the SB win % of the 2 seed will drop, whereas the 1 seed % will go up and I’d think the other seeds % will increase ever so slightly too.
