A +2.5 spread means the underdog will need to win outright or lose by one or two points to cover. Similar to what we explained in the previous section, a spread of +2.5 in football and basketball indicates a matchup of two fairly evenly matched squads.
In football, you could wager on under 2.5 goals. Then your bet would need to finish with two or less goals to work. Alternatively, you can select over 2.5 goals. Three goals must be scored in total for this to win.
