It matters a lot in sport's futures. It sucks to tie up money for the length of a season if same bet can be made on credit. With some of them a case can be made one is better off putting the cash into a CD given the length of the season and the small profit margins in futures betting.

My general opinion is the gambling tide raises and lowers all ships.
There are very few losers if any here and nothing but winners.
Although like all gambling projections the projections are ludicrous.
