We always hear about how when players are on holidays they need to follow some sort of fitness regime so that they come back to training in good shape.
How about as well as this the players get given certain kicking skills they need to work on in their break to be tested on when they come back?
Instead of just coming back and doing a 3 km time trial, how about coming back and doing a test to see who actually has spent some time working on on their skills for once?
