People forget that Stiles has been in the Reds coaching set-up since _the 2014 season_, this being his 4th year with the Reds. In that time he has solely attained an improved Reds' scrum for a period (which is but a fraction of what a good Forwards coach needs to improve overall, and the Reds' scrum has not been outstanding in 2017).
Not too dissimilar to Dave Wessels though. This is his 5th year with the Force though (I believe) and all that time they struggled. He took over partially last year (as did Stiles).
The most notable difference being the experience in the Assistant Coaches. The ARU were heavily influential in having Barakat and Gaffney involved. Shaun Berne is obviously a young coach, but at least with experience coaching in a highly professional outfit.
The ARU weren't involved in assistant coaching selection, I don't believe, and clearly selections were made for other reasons. Arnold and Gilmore have no professional rugby coaching experience and barely any experience coaching men. Most of us acknowledge that they were likely picked because of their low asking price (deservedly considering their lack of experience). I think we all acknowledge that was wrong. The decisions were made at a massive state of flux within the QRU. The new CEO was barely at his desk when appointments were made and the full depth of the financial problems were really being discovered.
If Stiles had some old heads around him this year. Not sure who but the likes of Scott Johnson, Brian Smith, Michael O'Connor, Les Kiss, Tim Lane would be worth considering (assuming they want an assistant role). Of course there are international options too but they would come at a higher cost.
