No need to walk you've got umpires to do there job and give them out. Most players don't walk and don't forget Clarke didn't walk when he nicked it the Adelaide game against England a couple of years or so ago, the same with all teams so it's time people get over Broad not walking. As for sledging anybody going over the top should cop a 1 game suspension imo. Some of the sledging is quite funny but when it goes too far the umpires should step in.
