Brad Arthur has also stated the obvious, no f**king rocket science necessary in Rugby League, just relaying what happens at training to the playing field. By saying he's not going to reinvent the wheel he really means he wants Parramatta to use the same wheels used at Manly/Melbourne, where he learnt to drive.
Like the top coaches he just wants the Eels to play the way he thinks, if his ideas are not satisfactory then his coaching won't be satisfactory . . . providing his players do as instructed. Arthur doesn't just want to win games, he wants to turn players into household names for the right reasons, that's not rocket science either.
The way Manly and Melbourne play is no secret, blind Freddy can see they wear other teams down with consistency and will power, player mindset is everything, only a basic IQ is necessary. Genius players have been made that way by the coaching they received along the way
