Maguire is a premiership coach, but comparing his time at WT with that of a coaching legend like Tim Sheens who is yet to coach a single game, is unfair. To start with Maguire arrived facing a club in big trouble. The CEO and previous Coach feuding and unhappy boardroom which spilt over to a lack of support to Maguire, who battled to balance a cap in terrible shape while being undermined by the board.
The thing to remember about Maguire's tenure is that he left the club in much better shape than he found it and that's his legacy.
Sheens otoh has 2 years to build on Maguires legacy, with a much easier run, particularly in terms of the cap.
