Agreed.The problem came in before the press conference... the minute they tried to cover it up. When the umpires came up to Bancroft (and Smith joined) it should have been pull at the yellow tape, apologise. Ball change 5 penalty runs. Sanctioned later and an apology. End off.... it was the attempt (between Lehmann, Smith and whoever else involved) to lie and try cover it up.... at that stage they looked really bad, and with the TV pictures anything but a full confession would have probably been worse.
Had they done this it would have been a story but not a huge one.
To borrow a line from Lord Melchett in Blackadder 2 thet twisted and turned like a giant twisty turny thing. In trying to deny the bleeding obvious they looked stupid.
