question

im not sure if this is normal or not so i thought id ask you blokes to get an idea.
i was at the pub friday thought id have a look at sportsbet, in the mayweather hatton fight mayweather was paying about $1.40 for the win hatton about $2.50. when it came to method of win mayweather was paying $2.10 for decision and $4.00 for knock out. seems a bit odd that such a firm favourite would be paying those odds for decision and k.o
anyone got some opinions to enlighten me?
