RuggaMatrix International 070 - Pure Speed

What a weekend of Heineken Cup quarterfinals and that's our main focus this week.

Former Leinster hero and current Wallabies captain Rocky Elsom gives us his view of the final 8 matches and what he thinks will happen in the semis.

As usual it's raw Rocky with some interesting thoughts on Leinster and the other teams.

We also look inside the Brumbies and the Super 14.

Les Kiss has the night off ... we'll catch him next week but we happily welcome back Ewen McKenzie fresh from a successful tour of South Africa.

This week we talk the Bulls which is the best match of the weekend in the southern hemisphere.

IN-DEPTH ANALYSIS - PURE SPEED

This week's IDA is inspired by the blinding pace of Zee Ngwenya, the American winger whose speed was on display again for Biarritz against Ospreys in the Heineken Cup.

It was a try that only Ngwenya could have scored.

But pure speed is not enough there must be a balance and Ewen McKenzie talks about the dangers of selecting on pace alone.

Playing without pace is equally dangerous so how do you get it right? Once again it's a masterclass in rugby coaching.
