I agree we traditionally go better with a Manly man as head coach, but the players have obviously bought in to whatever Barrett is selling and that is good enough for me.
We have only had 2 previous non-Manly coaches ... we have no idea whatsoever how we would have gone with more. It has always amused when I hear we only win with ex-Manly coaches ... when you don't employ anyone but ex-Manly coaches.
There are probably 2 main ways to rate a coaches' success.
1) Winning a premiership .... (given that only about 70 odd coaches have managed to do this in 110 years out of over 900 coaches would mean a lot of good coaches are considered failures)
2) Is the team/club in a better position than the one he inherited ...
