They got smashed all over the place in those 5 overs between them. So do you think we should of given KP a go as well then?
Joe Root should've been given a short spell on his own in tandem with Swann as Australia would have looked to score runs off him. It's called attempting to buy a wicket.
Edit: it's "SHOULD'VE" or "SHOULD HAVE". Sort it out Fawlty FFS.
