The commentators will be all over Steve Smith until or unless he gets a big score. His runs in Safrica will not be a topic of discussion until he succeeds. It won't be "what a treat it is to watch Steve Smith" like they do with Sangakarra and co when they tour. It will be - "this guy needs to prove himself away from home".
I expect some Ian Chappell like trolling by the commentators - but not quite as stern, hyperbolic or harsh as he is. The Aussie players best turn the volume off in the dressing room, because they will not like a lot of what they hear. Mark Richardson and Ian Smith appear emotionally invested in this series, unashamedly so. They'll give it to Smith if they can, and the crowd, if any, will look to give it to Warner.
