It depends on if Ibaka is 100%
If he's hobbled slight edge miami. If he's healthy OKC had the big advantage.
I can see the series playing out like this
Game 1 - Miami 97, OKC 105 - Despite 30-5-6 from Lebron James, Kevin Durant showed why he's the true MVP compiling a 40-10-11 triple double along with 3 blocks as OKC cruises to an easy game 1 victory.
Game 2 - Miami 89, OKC 110 - Led by 25 from Westbrook, OKC holds miami to 35% shooting and Serge Ibaka notches 6 blocks as Lebron James and D Wade combined to shoot 10-40
Game 3 - Miami 110, OKC 109 - A thrilling win for Miami as Ray Allen's 3 seals their victory as lebron notches a triple double and wade shoots 65% from the field.
Game 4 - Miami 95, OKC 98 - Kevin Durants stepback 3 gets OKC one step closer to their first championship. Despite 30 points from D Wade, and 25 from Bosh, Lebron shoots 3-16 as the combination of Kevin Durant and Jeremy Lamb stifle the former league MVP
Game 5 - Miami 101, OKC 102 - Wade's last second miss clinches OKC first championship as Kevin Durant notches 30-6-7 and Westbrook chips in with 19-11-8 as OKC wins their first ever title in Oklahoma City.
