There are no tracked defensive stats for giving up these shots, at least from what I could see. So in it's place I sorted each of our games(since the Suns game) took the number then compared and contrasted it with that teams average amount of wide open shots as well as comparing it to the league average.
I know it's a bit sloppy but formatting is Team Name(league rank in amount of wide open threes, how many per game) then how many against us.
Suns(takes the 3rd most wide open threes in the league at 25 per game): against us 18
Lakers(last in the league at 15 per game): against us 13
Rockets(19th in the league at 19 per game): against us 18
Pelicans(13th in the league with 20 per game): against us 23
Bulls(6th in the league at 22 per game): against us 24
Warriors (4th most wide open 3s in the league at 24 per game): against us 33
Warriors: against us 19
Kings
27th in the league with 16 per game) against us 19
Grizzlies: (7th in the league with 22 per game) against us 20
The Spurs are giving up an average of 20.7 wide open threes a game. The league average Wide Open three point shots per game is 19.8.
My take away from the numbers: There are, of course, improvements that can be made in this area, but it's not as bad as some people are making it out to be. We've only had one egregiously bad game against the Warriors.
Ultimately this is just another piece of improvement the team has had since we drafted Victor. I still remember the dreaded 18 game losing streak we had during Victors rookie season.
Now, we are almost a 5th of the way done with the season and currently rank 10th in offensive rating, and 5th in defensive rating. Just happy to see that improvement.
