I think Galvin probably slots into the centres.
We are short on quality there & don't necessarily lose anything by playing him ahead of some of our other guys.
Gets him on the field now. He's clearly quality. We lack that quality. Fittler & Daley started in the centres. Burton too (although I think he is over rated- he's possibly the best comparison to Galvin at this point)
The Tigers will only get better once we field as many or more high quality players as the opposition. This is why Galvin, Fainu, Lauali'i, Fa'agutu, Bula & Jordan Miller need fast tracking. When these guys are our starters & Seyfarth, To'a, Staines & co are our back-ups... we are a good team.
Benji, Heighno & Farah need to get these young guys into 1st grade shape as quickly as possible. No point having them physically outmatched. But once they are right body-wise, start playing them IMO.
