This i can agree with. Fully.
Would it be unimaginable for, say, Racing, Toulon, Toulouse, Saracens or Leicester (picking a pretty broad spectrum here, so give me some rope) to beat Leinster on a single-elimination round?
I don't think so. Most would be underdogs, sure, but they all got a fair realistic shot at it.
What is impressive and here is where Leinster is head and shoulders above the rest is how they've managed the transitions between what i call, generations. And it's not as if they're doing it a la PSG/Man City.
And, i gotta give credit where credit is due, they tend to show up when the **** hits the fan. They dont shy away, they dont choke. They have a plan, they stick to it, and if it doesnt work they adjust it at the trainer's/captain's discretion. And this is not by chance. This is a very, very well oiled machine and that speaks volumes of Leinster's management.
And, of course, they've got Sexton. He doesn't have Barrett's pace, Carter's flair nor kicking but good lord he's good. There are very, very few players that make me think, 'this guy's head is on another level'. He is one of those.
