Observe them for some time ? Well, are you sure they will have same team composition 7 years from now ?? Otherwise you will again say that they are a new team and in building stages :)
I am definitely not going to hope for the same composition or any composition where selection is not based on merit.
What I hope is that our team gets the "right" combination. And as I said earlier, if you have the right combination and sufficient opportunites then improvement does happen. If it still doesn't happen then you can rightfully label them whatever you want to.
