REBOUNDing
freethrows
defence
preparation
passing
You should know as much about your opponent as possible. Teams that go into games most prepared, give themselves a slight advantage
Like rebounding, defense is mostly about heart and desire. You win games on offence but you definately win Championships with defence.
Not really a part of the game that requires a lot of skill but rebounding is mostly about heart and desire. The best rebounders are the guys on the team that like to play a physical type game. These type of players are usually the 'unsung heroes' on many Championship teams.
A phase of the game that a lot of young players don't work on. A lot of games are either won or lost at the freethrow line. So if you want to become a 'clutch' player then being a good free throw shooter is essential.
A part of the game that is often overlooked. Everyone likes to score but someone who focuses on getting players the ball in scoring positions is just as valuable as the person that actually scores the basket.
