Phoenix was a lot more appealing when they were listed as +3.
It seems like veryone is all over Phoeniz, including the public money. Like you, that worries me a lot.
Plus, not many statistical advantages/trends favoring Phoenix in this game. I've analyzed The FoxSheets and can't come up with a strong reason to go with Phoenix.
With that being said, I'm going to stick with my parlay of Indiana (+5) and Phoenix (+2.5).
I have, however, found some strong trends favoring the UNDER in the Phoenix game. Look for Dallas to play very good defense at home, as the Under cashed in more often than not on their home floor.
