Is +420 good odds?
It depends on how likely the bet is to win, not on the number itself. +420 is a good price on a side that wins more than 19.23% of the time and a bad one on a side that wins less. If a market kept nothing, the other side of a +420 bet would be −420; real books price it worse than that, and the gap is their cut. At −110 on both sides, the most common spread and total price, the cut is 4.76%. Which book keeps the least differs: every sportsbook's cut, measured.
As a price, +420 makes the side a big underdog.
