It's a good point that Loveday & Smyth won coach of the year in the same year, as they both have about the same skill level as a coach. It's all well and good to say they took them to the grand final, but if you look at the teams North had they should have won a few of them by now. It's really in spite of the coaches that they have done so well.
The Rockets have had one of the best reserves teams over the last 5 years, consistently making the grand final. Then when it comes to mens, these guys all sit on the bench, whilst the reserves players from the other teams go and out get significant court time and play well. There's no point having a bench if you are just going to play your starters for 35-40+ minutes a game, irrespective of whether they are playing well or not.
The other problem is Loveday doesn't know how to put a team on the floor. It's all well and good to have a talented bunch of guys, but you need to put 5 guys on the floor who can play well at both ends. There's no point having 5 scorers on the court who all want their shots each game but won't do any of the little things or play defence.
If North didn't lose so many of their good players, particularly guys who played well as a team, they would have won a few more titles by now. It's not just the guys they've lost either, but also the players who would have come across if other people hadn't left.
