Isaiah's shooting percentage didn't really drop off late in the year. He shot 42.4% from three in the last 5 regular season games and 40.0% from three in the ACC tournament. His percentage didn't drop off until the NCAA tournament, in which he hardly played.Thanks for researching. This was exactly my point. For Evans to have a special season, he will need to shoot a lot more 2s. A good defender will just crowd you at the line and make your shots more difficult if you can't keep them honest by attacking the close out. I believe this is one reason why Isaiah's shooting % fell off late in the year.
I believe his poor shooting in the tournament was a lot more related to his lack of playing time than it was to the defenses catching up to him, and here's why:
Evans played 10 or fewer minutes in 14 games this season, and he shot 15.8% from three in those 14 games.
Evans played more than 10 minutes in 22 games this season, and he shot 45.4% from three in those 22 games.
It's possible this is a chicken-and-egg issue, in that it's possible that he appeared "off" in the 14 games and that's why Coach Scheyer didn't play him more. But since he only took two or fewer threes in 13 of those 14 games (and it's probably hard to tell if he's "off" after watching just two shots), I think the more likely explanation is Isaiah needs some time to get going so when he doesn't play much he can't get in the groove.
(Admittedly it's true he went 0 for 5 from three in the first NCAA tournament game in which he played 20 minutes against Mt St Mary's, though that 0 for 5 is included in the 22 games mentioned above and he still shot 45%, plus also I find it hard to believe that it was Mt St Mary's who magically found the formula to stopping Isaiah Evans.)
Ultimately, I think the fact that there weren't many (or any) starters in the NCAA this season with similar shot selection to Isaiah Evans does not mean it's a bad idea but rather because there aren't many (or any) players like him. Can you guess how many power conference players other than Isaiah Evans took 10+ three attempts per 40 minutes, had an eFG% of 60%+ and are 6'4" or taller? All right, you don't have to guess. The answer is zero. Just Isaiah.
You say that good defenses will just run him off the line, but they weren't able to do it this past year, and the way Duke ran plays with multiple staggered off-ball screens for him (along with his height and his very quick release) it's not as easy as it sounds to just run him off the line. If Evans can play 25+ minutes, and still get 10+ three attempts per 40 with an eFG of 60%+, then what's not to like? Why would he "have to" shoot more twos?
