One of the best-known and most widely accepted truths around here is that Jim O'Brien makes the Pacers take too many 3pt attempts. I don't remember hearing that about Carlisle or any previous coach, but O'Brien gets hatred because the Pacers shoot "too many" 3s. Well, lookee:
This is the Pacers' 3pt Attempts (the bars, scaled on the left side) and 3pt percentage (the line, scaled on the right axis.) for every season since 1981. Note the strike-shortened year in 1999.
It doesn't take a genius to see that 3pters have increased steadily over the years. The Pacers' use of the 3 has grown with every coach except Irvine and Thomas. Even Rick Carlisle raised the team to a new high in 3s. And with his slow tempo, that is saying something!
Yes, O'Brien has pushed the team to new heights, too, but you can see a big boost in the percent made under O'Brien, too. He definitely did something right in his first two seasons.
I would be curious to hear comments about how high the number of attempts can go in the future. Reasonably, as long as the eFG of 3pt attempts is high enough, the team should continue taking more. (Note, when I say the future, I'm not talking about the rest of this season, but beyond that.)
To refresh your memory, here the Pacers coaches since 1981:
