If you choose the Cowboys, they must win or lose by less than 7 to cover.If you choose the Eagles, they must win by 7 points to cover.
Say the Eagles are 6.5 point favorites (-6.5) against the Cowboys (+6.5) and the total score may be set at 48.5 points. These cards include “traditional” lines including point spreads (favorite/underdog) and totals (Over/Under) that are not adjusted at all as they are in teasers.
