He probably averages the most in every position in the side. He's batted at 5 three times in the last six years, probably when there was a nightwatchman. He'd be wasted at 5 as our best batter.They can talk all they want about "leading from the front" and "taking personal responsibility" and other babbling, but the sample size is big enough to show that at Test level Root is a number five already batting out of position at four
(that is quite aside from him also being thoroughly out of position as captain)
