Most unfortunately Ireland missed out on the chance of setting the 'Perfect 28' 6 nations point score last Sat by not getting the 4 try bonus point, after fluffing 2 decent last gasp attempts.
As in 5 Wins with 5 Bonus Try points and the 3 point Bonus fer winning the Grand slam could have taken them to an ever unbeatable 28 points, similar to the 9 dart finish, or the 147, or the perfect 300 in bowling, Etc, it can be matched but it can't be beaten.
