2-3 zone Defensive Matchups
3pt - More likely PG or SG will be the defender but small chance the SF or PF will defend
Jump shot - PG, SG, SF, PF all have the same chance to defend the shot (I think this is where it suffers the most)
IS - most likely the C will defend, SF and PF have a good chance, PG and SG have a small chance
if you watch how a 2-3 zone functions in real basketball, that's a pretty accurate analysis of how they guard offensive players. PG/SG patrol the top of the arc and SF/PF guard the sides, moving out to the perimeter as needed. SF/PF can also collapse around the basket to help the center.
According to this, to build a team for a 2-3 zone team, you need:
1. High OD on positions PG, SG, SF, PF
2. High ID on C, PF, SF
To beat a 2-3 zone in real basketball you need a lot of ball movement (passing) and dribble penetration (driving), so the zone collapses in towards the basket and leaves an open shot. The zone naturally rotates to focus on the ball handler, so with enough quick passes, it will leave the back side of the zone with one defender trying to cover too much of the floor.
An offense that doesn't have these passing/driving capabilities will tend to just shuffle the ball around the perimeter and take a contested 3pt shot. There are a ton of youtube videos on the strengths and weaknesses of a 2-3 zone defense. It is not as weak as it is in BB.
Right now if BB's 2-3 zone success relies on having crazy high OD/ID, I would suggest relieving some of that defensive burden and put it on the offense to have better driving and passing capabilities.
