Portland at Phoenix

Is this line really just 13.5? Phoenix should be favored by closer to twenty here. The Suns have picked up their play, especially at home. They are 4-0 SU and 3-1 ATS in their last four at home where they are pouring in nearly 104 per game. They've won their last five games by an average of 13 points. Portland hasn't scored 100 all year and are averaging just 84 per game. Bigger mismatch than this line reflects. Two stars on Phoenix minus the points.
