He was but Mason did have good durability and some power whilst I think Golota is a level above Mason. I wouldn't make Golota a huge favourite because he's such a head case that if Mason can hang in there and land some power shots he may make Golota doubt himself.
For me Gary stops Golata late. He was almost a poor man's Ray Mercer. Great chin, methodical, good basics and heavy handed without being explosive. Golotas fragility between the ears sees him looking for a soft place to fall after building up a comfortable lead with litte effect on Mason whose train just keeps rolling...
