Celtics blogger expects Boston to beat Spurs

Tonight the Spurs and Celtics will clash in San Antonio and Celtics blogger John Karalis of Red's Army weighs in on the matchup. In a nutshell, John is expecting the Celtics to shock the Spurs tonight and escape San Antonio with the win. Here is what he had to say on tonight's Spurs-Celtics game.
So the Celtics have played a double overtime game where Paul Pierce and Kevin Garnett played 40+ minutes and Rajon Rondo played on 52… then they played a disappointing game against the Rockets.  Now, they face a damn good San Antonio Spurs team on a back to back. 
Recipe for disaster?
Totally. Which is why they'll come out great, and win this game. 
Yeah, I know. It's crazy. It makes no sense. Which is why it makes sense.  
This Celtics team makes no sense.   And they get up for big teams after disappointing losses. I've learned that the best way to predict the Celtics this season is to take conventional wisdom and do the opposite.  Yes, the Celtics are "George Costanza." If every instinct you've had about them is wrong,  then the opposite must be true. 
Conventional wisdom calls for them to lay an egg. That means they'll shock everyone.
