Portland has a brutal road schedule coming up and has played some tiring up tempo games the past few days. That being said they are hot and talented and taking on a Thunder team lacking the services of Russel Westbrook. I can see this game being close and OKC winning outright but not by more than 5 points. For the record, Portland has won both previous match ups outright and both of those match ups were close games.
Going with....
PORTLAND TRAILBLAZERS +5.5 at THUNDER
