NRL Round 13 advanced statistics – Involvement Rate

Involvement Rate is an advanced statistic for rugby league that I created to identify players who have a high workload but don’t play a lot of minutes. Traditional rugby league statistics are counting stats and volume based, and the important work of middle and interchange forwards goes largely unrecognised.

If you’re new to the site and want to understand how it works, I would recommend reading this post on Involvement Rate. To put it simply, it is a combination of Run % and Tackle % which shows the estimated percentage of plays that someone completed a run or tackle during their time on field. Basically how much work they were putting in.

Adjusting for minutes played and times helps identify those middle and interchange forwards who play with a high motor but don’t play huge minutes. Think Daniel Alvaro, Christian Welch, Blake Lawrie, Moeaki Fotuaika, Toby Rudolf and Francis Molo.

With that out of the way, here’s the all minutes leaders for Round 13

Billy Walters took top spot for the week in his 14 minutes with an Involvement Rate of 29.09%, before succumbing to a devastating knee injury. Hopefully he makes a full recovery and we see him back on the field early next season. Site legend Daniel Alvaro was second for the week, with an Involvement Rate of 27.82%.

Rookie Shaun Blore continues to impress for the Tigers as well, placing fourth with an Involvement Rate of 25.84% in his 23 minute on field.

Next we’ll look at those players who spent 40 minutes or more on field

Nelson Asofa-Solomona places first this week making a tackle or run on a quarter of all plays whilst he was on the field during Melbourne’s win over Canterbury. Tevita Tatola (22.79%) and Toby Rudolf (22.75%) round out the top three this week.

Finally we have the leaders for Involvement Rate this season

The Titans Rookie Jaimin Jolliffe has maintained his grasp on the top spot ahead of teammate Jarrod Wallace, with an Involvement Rate of nearly 23%. It can’t be said enough how impressive his season has been from a workload perspective, and he shows no sign of hitting the rookie wall.

Jazz Tevaga (22.37%) from the Warriors has rapidly moved into the top three this season after just five games, and could even challenge for top spot if his minutes and workload stay at this high level, being only half a % behind Jolliffe.  

The top five is rounded out for the season by two Storm players, Asofa-Solomona (21.40%) and another Eye Test legend in Christian Welch (21.36%)
