I think the issue isn't his surname, it's that he's learning a new position in 1st grade.
What is the point of having a reserve grade team if you're not going to use it?
The issue fans have with him is his surname.
The issue with Sironen is that he is an old school lock, who doubles up as a ball player. That role doesn't exist anymore in the forwards. The closest position to it is at centre.
He has the mentality of a ball player in the frame of a back rower.
It's not as simple as just shoving him in the forwards and thinking it'll just work.
He needs to be retrained about how he plays the game, from scratch. He is physically capable of the role of backrower, mentally, he's still a five-eighth.
Fixing that is going to take time, doesn't matter what grade he is in.
I said it heaps of times, he should have played in the centres all year this year, it would have allowed him to still use his ball playing skills, while also learning the basics of back row play, such as defensive positioning, cover defending, running lines, running decoys, timing runs etc. Simple little things that he would have sweet f**k all experience with in his career prior to this season.
