True, but that would be the only time that an international manager can try new players, otherwise it's throwing them in at deep in in competitive matches. I would suggest the real problem is not too much international football but too much club European football, but then we all know money...
The only thing I think I would change is having a pre qualifying tournament in Europe for the minnows and therefore smaller qualifying groups.
Unfortunately, money talks and the administrators of the game just want more and more.
