No-one really engaged with my last contribution but I think the make-up of the Australian side is interesting so I'll have another go.
You have five batsmen, one of whom bowls a bit of pick 'n' mix legspin. You have a respectable keeper-batsman, though he's not as good as he was. You have two or three bowlers who could handle batting at number 8, and your number 11 averages 15.
If you then had to choose your 11th player - either a number 6 who'll average 34 with bat and ball, or another number 8 who'll average 27 with bat and ball, which would you choose? (In effect, if you could be certain they'd play to their career averages, would you pick Watson or Pattinson for the 11th position?) What would be needed to change either way? Eg, if either of those players were a second spinner rather than a fourth seamer, or if your keeper batted like Sarfraz Ahmed or BJ Watling of the last 18 months rather than Brad Haddin of the last 18 months, or if Pattinson's economy rate was closer to that of Watson.....
