Lord Coe's position looks untenable now. Caught lying about his knowledge of the allegations about the Russian doping scandal, he should now resign if there is to be any hope of cleaning up the sport.
If you get caught you pay the price. That may only be a 2-year ban in athletics, but Coe is the man at the top, and if he was covering up the allegations against Russia he's toast, surely, just as Big Sam was. If he resigns he'll get an equally large pay-off too.
