Creating propositions for individual games is more work than I'm willing to put in. I'm done with that for now, and have instead created a couple propositions surrounding the playoffs, based on the winning team's division and conference. The op has been updated with some info, here are some links:

By the looks of it, Central division has the most teams in the highest league rankings and might be the winner of the Stanley Cup. The whole Western conference has a strong presence in the ranks this year, the chances of them winning are high I believe. It's pretty crap that there's still no Canadian teams in any position in the playoffs, but whatevs.

Happy betting, good luck to all bettors!
