Looks like 75-1, not 750-1. I don't think he'll win...this year. I just like the publicity! Changed the thread title. I didn't realize ESPN gives the entire field 30-1 odds.
Before seeing this post, I actually put $2 on Purdy and it was 750-1 odds. Said $2 would win $1500 (and some change), so it is actually 750-1. Don't think he will win (and my bet cashes), but I had some extra money from the NBA Opening Night promo they did so figured why not.
