Possible new contest - Spread Game

Would anyone be interested in a new contest that uses the spread?

I never understood the spread until I read up on it (here's a good site www.quora.com/what-does-covering-the-spread-mean-in-sports-betting)

I think I could set up a contest, similar to the total wins contest spreadsheet which we could run if there is interest.

Or we could wait until next year.

Thoughts?
