MIKE: did slightly above average at his usual position (CHASER) and average at his new position (BEATER). He is out of practise and had to work hard to make the Hogwarts team to start so he is no natural on the field. He only had usual bruises.
ALBUS: did fine at his usual position (KEEPER) since it hasn't been too long since he was at Hogwarts, but needs plenty of work at his new position (SEEKER). He surely got banged up a little, but no permanent damage. He has plenty of scrapes and cuts that need cleaning!
DRACO: his head isn't in the game. It isn't anywhere lately. He fell and he doesn't want to talk about it (though he really bruised his tailbone and is in pain).
