Are you looking to determine just the relative probability odds of each team making the playoffs? Or whether or not specific teams have mathematically clinched a playoff spot, other eliminated, etc..? There is at least one phone-app that does the former and probably other programs available, or its not too difficult to make a program via spreadsheet that goes through the remaining schedule with random outcomes a set (say 10,000) times to determine how many times each team finishes in the top 8. For the latter, do a search for "calculating playoff clinch" or similar wording. I'd mention one site in particular but I don't want to be accused of violating this forum's TOS
