My dd played a season for CB and still gushes about him. I personally like CB very much, so my comments to follow are definitely biased....
When my dd was on CB's team two seasons ago, CB used the Spring EGSL season to give players from the SOC B and C teams a chance to play with the A team. What is wrong with that? The spring league games mattered for nothing other than formalized scrimmages for the teams. CB never seemed to care about winning during these games. He moved players into different positions throughout the season and games. Again, what is wrong with this strategy?
Now if CB went to the parents of the B and C team players and promised them spots on the A team if they played for him during the spring league and then did not fulfill this promise, okay I would be pissed too. However, I don't think that is how CB conducts himself.
