Deans' top league side hasn't lost a game in 4 years. Granted it's a bit of a Mickey Mouse comp, but it's still an impressive feat
It reflects how the less involved Deans is with the actual hands-on coaching of teams, the more beneficial his influence is.
Much like Hansen, Deans is a great big picture guy - team direction, vision, and a very large emphasis on the holistic approach to managing rugby players. This is why Wild Knights are doing so well, it's with him overseeing the entire operation as more of a director of rugby type guy. He's also great when it comes to the recruitment side of things, he's identified cast-offs in Australian rugby like Riley, Semisi Tupou, Cornelson, etc.. and has gotten the best out of them as players by selling them a dream, giving them an opportunity that others weren't willing to.
So ultimately he's got excellent management skills, good at talent identification and understanding of elite pathways & in developing high performance environments. In my opinion his strengths are more suited to a Director of Rugby role overseeing vision/direction & high performance than a technical hands on coach.
He'd do probably do best in a David Nuicifora (ala-Ireland) high performance/DOR type role in my opinion, but history has proven he's not a great hands on coach, technically he's not strong, as evidenced by how average Australia's attack (2011-2013) during his stint as backline coach after Richard Graham left (
see article below) and how similarly ineffective he was filling the same role for the All Blacks under John Mitchell (2001-2003).
By the stats, is Dingo Deans the man to unleash the Wallabies attacking potential on the British and Irish Lions tour? Let's find out.

TLDR - Deans isn't a great coach, he's a great manager. He's NZ's equivalent of Clive Woodward, put technically proficient coaches around him to do all the hands on, on-the-grass coaching and have him responsible for the higher up organizational management fluff, grand scheme & high performance stuff. That's more or less how England succeeded under Sir Clive in 2003.
