I have seen what has happened to both the U21 team and the National team this season.
The only thing that can be said is that winning matters.
So when a coach starts emailing directives, commands, wishes or whatever for training, believe you me, those managers are more apt to listen when you are WINNING.
Case and point. Look at Furuzawa. During Nippon U21 run to the best 12 stage of the Asian championships, my close and personal relationship with his manager helped but U21 Japan and the managers team. At one point, the manager even considered giving him PASSING training right before the start of the NBBA playoffs.
What manager in that position would listen to a coach that WAS NOT WINNING? This goes for several other players during that run.
The U21/NT coaches must realize what those wins mean. Japan should not be losing to Kazakhstan or Macau. It may anger managers from those countries, but we just shouldnt be losing those games.
The key to these jobs is finding manager that relish in the fact that they are training a very special player...not reprimanding managers for training THEIR OWN PLAYERS the way you want them to.
You must establish harmony at the beginning of the season...especially when there is promise. The worst thing you can have happen is for a disgruntled manager to sell his player during or right before the season starts...which happens way too much for the Japanese teams.
WAY too much.
Somebody let me a hold a no. 2 pencil cause they testin' me.
