So??? Your friend Grounder himself said statistics are like a bikini, & they don't matter. He says it doesn't matter what the batting average of a person is, but how he destroys his bowling opposition. As Shahid Afridi's higher batting strike rate indicates, he destroys the opposition better than Sehwag as well.
why u taking in isolation about batting average and strike rate ? U have to found the person who is best on all parameters.
