Plenty of CHF and FF have the same build.That's a different comparison, full forwards and Centre half forwards have different physical makeups. Cricket is just not getting out and scoring runs.
Almost all batsmen come into the test side at 5 or 6 and cut their teeth before they move up to 3 of there amazing. There isn't really such thing as a good number 6. A number 6 is either a temporary batsmen or a temporary number 3 or 4
A number 6 needs to be able to face an old ball/pitch, and steer the direction of the innings. Khawaja struggles with the old ball, and when the ball starts with less predictable movement.
I'll let my mate know to get in contact, I'm sure they'll throw coin at you two, since apparently coaching is pretty simple and every batsmen can bat in every spot.
Khawaja is on better terms with the coaches and players too, if khawaja was a better choice at 6 than maxwell he would've played. But he's not.
