unless you have previous data, its really difficult to assess early doors IMO
a gauge on fitness is probably the easiest to spot early.
i always start with the basic 3 of striving,achieving and forging ahead. and these 3 can be seen in the first few pratice sessions.
when i took over the u16's it took me nearly half a season to understand properly the 20 players i had and that was from recording data in training and matches
