Mayweather v Berto line movement

All the money has been on Berto. The line started at 100 or 80  to 1 depends on where you went.

This is what always happens, that is why the odds are set up this way. Otherwise everyone would bet Floyd (and most importantly Vegas doesn't make money).

The average bettor plays small, so if you bet on Floyd, you risk a lot to win a little. If you bet 20 on Floyd, you win a buck, if you are lucky, bit 20 on Berto is 400 or more. Most people bet to win big (which almost never happens). They dream about the results (bet on possibility) instead of reality (probability).
