It was a close fight, there was definitely no robbery.
If Cunningham had been more aggressive, he'd have won. But he ran too much and didn't throw enough in some of the rounds. He just jabbed, he should have thrown more power punches.
Adamek landed far more power punches according to the statistics.
When Adamek would hit Cunningham, BJ Flores would say "hard right by Cunningham". Likely many viewers were influenced by the jingoistic commentary.
