Yeah, he must have some personal grudge or whatever. Basically everyone in darts always talks about Smith like one of the nicest players around, he never really says anything bad about anyone, even after winning his very first world title he started rushing off to family, but quickly turned around to first shake his opponent's hand, and then went to his family. Barely ever any weird antics or unsportsmanlike stuff, almost always gracious in defeat as well.
No, people who say Smith is another idiot just can't be taken serious...
