You can credit the Lakers offensive rebounding. The Lakers had twelve offensive rebounds, three alone by Dwight Howard in the first quarter making the difference in scoring.
You can credit the passing ability of Rajon Rondo for this win. He passed Scottie Pippin last night in all-time postseason assists. He surpassed Kobe Bryant in the previous game. He is now the 8th all time behind Steve Nash.
You can credit the refs who called a lopsided game. LeBron James does not get called for offensive fouls despite extending his arm repeatedly.
