They're kind of polar opposites but the same end scenario with a common theme.
The common theme is they're both very bad kicks.
Other than that, Wines doesn't get enough cheaper touches on the spread. Taranto doesn't get enough quality touches on the inside.
As the pizza man said, he's a woeful kick (his numbers are worse than basically all ruckmen in the league) and that is compounded by him thinking he's a good kick and having a very high K:HB ratio. He's actually decent by hand, good even.
The other major problem is his kicking is so bad it leads to a lot of clangers which just cripple him.
Disposal can change, a more inside role would almost certainly damage his DT but would almost certainly help his SC, more contested possessions and less chances to kick instead of handball. That first season when his DE% was actually decent he had a 1:1.1 K:HB ratio and basically his ratio has gone more kick oriented as his DE% has gone downhill.
I still don't dislike the pick, that raw DT ability can translate to SC but he's got so little scope for improvement in DT that realistically you're projecting him both getting back to that level but also fixing the ratio destroying aspects of his game. You'd want to see some improved kicking and decision making and a perfect role.
My biggest concern is still Tom Green, he's just a much better prospect and fit for the inside midfield role and should be their top priority and with Kelly, Coniglio and Hopper already there it's hard to see where the 110+ role sits. Let's say Coniglio and Hopper stay as mid 90s guys and Kelly stays as a 110+ guy, if Green does what he looks capable of and pushes towards the 100 range that's already one of the top midfields. Throw in Whitfield, De Boer (not taking points but minutes), Greene, Ward and anyone else pushing through and it's definitely congested.
Still think Taranto is that guy you'd pick and not even question as a forward but that extra level required in the mids makes it a tough sell. Kudos to anyone with the balls to pick him when it works though
