clock...
score (not like THAT, but I make sure team who scored gets the right points..learned early on in summer league that you can NOT trust the table, even with THIS)...
when I started, i was taught after every basket, to glance at the scoreboard for time purposes, correct oints, etc. leanred this summer to pay even MORE attention with 16 yr olds at the table texting/chatting on their phones instead of working!!
off hand mechanics...
'communicating' with coaches
still watching my primary, being more aware of secondary and being aware of what my partners are calling without watching THEIR area too...
