Think he must have been mentored by Mark Bailey during that period.

I,m almost sure he first came to the club as a scrum half, filled out a bit and moved out to the centres.

If he's a forward there is a good chance he will play in the halves this season.

Josh played most of his junior rugby at Stand Off with Chorley Panthers up to U15s then moved to Blackbrook for U16s season playing at centre and helping Blackbrook win the NWC premier league title that year. He then stopped playing amateur rugby to join Saints U18s squad with a number of other Blackbrook teammates inc. Joe Bate, Marcus Baines, Danny Jones, Ste Yates and Callum Welsby.
All these lads went on the Saints tour to Australia in 2009 where Josh played in the centres in all 4 games.
For me Josh never had outright pace to be a top draw centre. His future lies in the second row or loose forward in my opinion.
I'm sure Rogues will add to my thoughts!

Yeah, pretty much spot on that. He isn't, and never has been a 'natural' centre, but he has always been solid defensively, and if partnered with a quicker, more attacking styled centre, he would - and has proven to be great. It's also worth noting that he has played quite a bit at 13 since joining Saints, and that is where he is at his best in my opinion.
