Stat Attack: GPS data underscores Best's huge involvement in Knights win

If it seemed like Knights rookie Bradman Best was everywhere in an impressive 34-18 win over Canberra on Sunday, that's because he was one of the busiest players of the entire round.

Telstra Tracker data recorded 33 ' high speed efforts' from the 18-year-old centre – the most of any player of the round and more than any player managed in the previous round.

High speed efforts refer to the number of separate times in a match a player accelerates to a running speed above 20km/h.

The category is regularly dominated by backline players but it's rare for any player to reach 33 in a game, with Best racking up 15 carries and 24 tackles, highlighted by two tries and two try assists.

His 33 was one clear of evergreen Roosters centre Josh Morris (32), three more than his own centre partner Enari Tuala (30), who last week covered more distance than any other player, and two more than Jesse Ramien and Dan Tupou (both 28).

In other Tracker findings, top speeds were down in round four which was the first round this year in which no player reached 34km/h at any stage. Warriors winger Patrick Herbert hit the weekend's top speed with 33.6km/h while Alex Johnston, Hayze Perham, Kyle Feldt and Curtis Scott all passed 33km/h at some stage in their respective matches.

With no 90-minute draw in round four, the maximum distances dropped with no player covering more than 10km.

Newcastle were again heavily involved though with halfback Mitchell Pearce (9.6km) covering the most distance and Tuala (9.5km) the equal-second most. Kyle Flanagan and Luke Keary (both 9.5km) and Corey Norman (8.7km) were the others to get through plenty of running in round four.
