Since 2003, when a team has lost twice in a series and loses Game 3 by 20 or more, those teams are just 20-32 (38.5%) straight up, 21-31 (40.4%) ATS in the following game. They are 2-12 straight up on the road in that following game.
Dogs in an elimination game, after losing by 20, are 10-24 SU (29.4%) and 15-19 (44%) ATS.
And teams to lose by 20 and then facing elimination in a potential sweep on the road are 3-6 straight up and ATS.
