I think the jury is still out on Gutho as fullback. Having a look at the 2019 stats, mostly against Tedesco, RTS, TT and Ponga, he looks deficient in terms of line breaks and average running metres. And he touches the ball a massive amount of times, which would inflate his ball playing stats.
The other way of looking at the amount of touches he gets is that he has the highest involvement rate of those mentioned. If that leads to the highest of any positive stat, LB,s LBA's TA's, then I dare say that's a net positive.
I'd also add on the average meters run front that Gutho suffers there on lack of kick return meters, now it might be that he's just poor at returning kicks, or it might be that we have other guys who are much better at it. Or it also might be that he very very rarely drops the ball and merkins would rather kick to the likes of Fergo or Sivo
Run meters minus KR meters
Turbo 177.5 - 45 = 132.5
Tedesco 205 - 65.5 = 139.5
RTS 206.2 - 65.5 = 152.1
Ponga 127.9 - 39.4 = Pretty shit acttually
Gutho 161.5 - 40.3 = 121.2
So not all that far off Turbo and teddy.
