In listening to LeBron's presser, he mentioned CJ Miles being a guy that killed them in the regular season. So out of curiosity, I looked up his numbers for the series:
2.8-6 FG, 1.3-4 THREE POINTER
So he shot 46% from the floor, but just 31% from three. CJ made 5 threes in 4 games. I'd say the Cavs did their job on him.
MEANWHILE as bad as PG was killing them for 2.5 games, the change in strategy clearly ended up working (although maybe he wore himself down as well). George was 15-49 from the floor in games 3 and 4, and just 8-24 from three. He ended up shooting just 38.6% from the floor for the series.
Teague was the killer this time around. The Cavs were content to let him get his shots off, and after going 43%/28% two years ago and 34%/27% last year, that strategy had a lot of evidence to suggest it was a solid one. This year, he shot 49%/53% well above his season averages, and his percentages the last couple of times he faced the Cavs. I'd have to rewatch, but it seemed they let Teague get more open looks than the last couple of years, in part because they were so focused on Miles and George.
