But they arent. I watch a ton of BBL cricket and you see scores of anywhere between 80-220 odd. It varies between games based on the quality of batting and bowling and pitch conditions. Bowlers who bowl well in the format take wickets, are hard to score against and restrict batsmen. Batsmen who play the format well score quickly, on short notice, and have good match awareness knowing what to do when.A white ball does not move off the straight; which significantly reduces the difficulty of batting to the extent that huge scores are a formality.
Come on, be a bit more curious about the format, there are different skills than traditional cricket, but that doesn't necessarily mean it's not skilful.
