Last year I thought was the first time that we used Crane correctly in red ball cricket. And one innings into this season, we're doing likewise.
Bring him on when wickets have fallen, and it's the lower-middle order and tail batting. Keep him away from the top order. Let Dawson (or Organ last year) do the donkey work/holding role.
Against the top order, they can usually just sit in and wait for the bad ball. That then sees Crane's confidence drop, and the bad balls become more frequent. And the cycle spirals.
But against lesser batsmen, who can't pick him, he can get himself into a grove. He blew away 6 to 10 last season.
