Curious to know why you look past Simpkin's disposal (clanger count 67 last year) yet scrutinise Taranto's (38 last year) so distinctly?
Wouldn't say looking past but there's a couple of reasons I'm not as focused on it.
1. Simpkin is more contested (just the nature of the stat outside butchers).
2. Simpkin has a far better kicking efficiency to the point of being closer to the very good kicks in the position than Taranto is to even the bad kicks.
3. 40% of Simpkin's clangers are FA, only 27% for Taranto. This further supports point 2 of Taranto's terrible kicking being a major issue for his scoring. Simpkin's is very much an outlier, most players are around Taranto. Could be a discipline issue for Simpkin but I'd expect more an outlier that will correct, especially as he gets a bit more umpire respect of being a good player.
4. All the other good stuff that Simpkin does led to a very favourable ratio last year. He scored 5ppg less in DT to produce 9 more SC.
Basically I can see Simpkin significantly increasing his DT output and I've seen nothing to really suggest his ratio would fall significantly (positive 3 years running), basically if Simpkin and Taranto both got to 105 DT the reasonable expectation would be that Simpkin is 110+ in SC and Taranto is <100 based on their careers to date and underlying stats/ratio.
In short, Simpkin's problem is quantity and Taranto's problem, historically, is a distinct lack of quality. In general quantity is historically a far easier thing to fix and improve.
That doesn't mean Taranto can't fix it, being more contested and kicking less would both help him immensely as would, obviously, kicking the ball better. Although must be said being more contested may hurt his marks, a DT strength. Last year Taranto did play more contested than previously but his kicking got even worse so even that might not be the fix.
It's hard to understate how bad a kick Taranto actually has been. He's worse than almost every ruckman in the league (he can thank Darcy and ROB, just!), he's over 6% worse than Dunkley, 8% behind Dangerfield who are noted butchers, he's statistically the worst kick of the entire Giants' squad.
Again, I like Taranto but until I see some evidence that something has changed regarding his kicking it's really hard to see his ratio (his problem) change. He'll probably be in my DT, no one is tagging him and if anything other teams will try and get the ball in his hands compared to Kelly, Coniglio, Whitfield or Green but that doesn't help in SC if he kicks it to the other team!
