This road trip is going quite well for the Celtics. They have covered all 4 games by at least 6.5 points. They have won 7 in a row and 5 of those games by 12 points or more. Their second team can do damage and they have plenty of strong three-point shooters who can fill the void should they rest some starters. The Spurs are allowing 123.3/G over the last 15 games (29th) while Boston is first at 107. The Celtics are +8.2 in that span and the Spurs are -1.8. San Antonio has covered 4 of their last 5 games and playing better, but running into an elite team priming for a title defense and clamping down defensively. I'd play this up to 14.5.
