A big factor in opponent shooting percentages is all the easy putbacks they get due to our weak defensive rebounding.
Interesting theory. You got me looking for some numbers to see if it's accurate. I'll have to email one of my stat guys and see if they have this number precisely. In the meantime, here are some team-level numbers regarding the Wiz and opposing shooting percentages:
At the Rim- 9th most opponent FGA at the rim -- 30.7% of opponent FGA (average is 29.7%)
- 2nd worst opponent FG% at rim -- 69.1%; (avg. is 64.1%)
Presumably, a fair number of putbacks would come from this range. But, it also includes dribble penetrations, at least some post-ups, breakaways...
3-9 Feet- middle of the pack in attempts
- 2nd best defensive FG% from this range -- league-wide, only about 14% of FGA come from this range
10-15 Feet- 7th fewest opponent FGA from this range
- 7th worst dFG%
Thought unrelated to the role of offensive rebounding in opponent shooting percentages: It's actually a bad sign to give up so few shots in this mid-range. You want opponents taking mid-range jumpers -- you want to take away "at the rim" and 3pt attempts.
16-23 Feet- at the league average in attempts
- 5th best defensive FG%
Threes- league average in attempts
- 5th worst defensive 3FG%
For last season, there was a very weak negative correlation (-0.49) between opponent "at rim" FGA and defensive rebounding. In other words, there was a very slight tendency for good defensive rebounding teams to allow fewer at-rim FGA. The at-rim FG% correlation was weaker (-0.36). There were slightly stronger positive correlations between mid-range jumpers and long twos and good defensive rebounding.
Interestingly, there was a nearly identical correlation (-0.47) between defensive rebounding percentage and opponent 3pt FG%. Bad defensive rebounding teams give up a higher 3pt percentage?
Of course, it's tough to say which way causation runs. I'll ping my guys and see if someone comes back with some stats on putback percentages.
