Hi

Im having a little trouble grasping the true MVC concepts. Models should be fat right and controllers skinny and views dumb?
I see the whole Holder concept - a container for multiple pages/objects of same type - But im not sure where to put the CRUD logic. In the holder controller?
The site im working on has several teams with several members. All CRUD is handled by the users in the web frontend and not in the CMS. So to add a new player/member to the team needs an addPlayer action. Would this action be on the TeamHolder or on the Player class? It doesnt make much sense to have an object that adds itself to another page. So since the Teams has players maybe the actions should be handled there?
From the modules I find on the website I think that the Holder classes are also used for CRUD operations.
Could someone perhaps enlighten me?

Thanks!
