Both are sloggers, so don't count on them unless the pitch is flat or the ball is already old. Their keeping has been above average, though Haddin is a bit more hot and cold; he has some great takes but also more than a few horrendous moments. He's a given for both highlight and lowlight reels.
Haddin has had plenty of irresponsible moments while batting in crucial moments. Prior certainly not as irresponsible, though his second innings in Adelaide was selfish and a poor effort even if he put runs next to his name.
