"Each of the 30 [NHL] teams was rewarded three lottery "balls" to start the process, but lost one for each playoff appearance over the previous three seasons and for each time it had selected No. 1 overall in the previous four entry drafts. To make things interesting, the NHL guaranteed every team at least one ball, which means that elite teams that had qualified for every Stanley Cup playoff over the past several springs still had a shot for the No. 1 pick."
