Zaurbek was really rusty coming of 10! month layoff due to promotional difficulties (visa problems i.e.). This was a Baysangurov at about 50% and he felt uncomfortable with the situation fighting at an attendance of approx. 14.000 people.
Poor excuses that shouldn't have been given if Baysangurov was a true champion. He didn't "beat" Bayram for the EBU title. The decision is not a scandal of course but I had it a draw and for such a close fight it would have been fair.
You have to be ready for a title fight and a 10 months layoff is not unusual in modern boxing, it's normal. About the pressure he was not in the main event and he had his amateur background. Watch fights with the young Juan Diaz. Truth is that Baysangurov was unable to dominate Bayram in terms of technical skills.
