Think of it this way. The longer you run the simulator the closer you will get to the sabres coming up 20% of the time.
Or in terms of the field Sabres have an 80% of not getting the 1st pick.
I too have been running the simulator in short sample sizes and I am getting the Coyotes, Oilers, Leafs and Flyers more than the Sabres. Coyotes being the most.
