(186170.1) got into 2-3 and SFs a bit.
it is worth thinking about what a 2-3 zone looks like compared to a man-man or any other defense and then compare this to the attacking teams offense/players skills
i take it the offense we are looking to counter is Look Inside and the focus here is at SF position.
If the team is playing Look Inside they either have the advantage/relative strength at PF/C and may play a PF at SF.
what they will do is try to get the ball into the key with a drive or pass for an inside shot or short jump shot which suits this situation.
so whether or not you play man-man or 2-3 you need an SF that can handle himself around the basket (decent ID and REB).
the advantage of 2-3 is your SF is more likely to be inside than outside on defense compared to man-man when the shot goes up (good for rebounding) or when his other inside buddies get beat (contributes to team ID/help defense).
the zone also means you end up with a mix of your 3 inside guys challenging their shots around the basket rather than each position matching up in man-man.
an sf with poor id/reb (also known as shooting guard) will leave a vulnerability to an opposition SF/PF playing the SF position whatever the defense
