He didn’t become a good shooter lol. He had two games where he got hot and went 8/20 from 3 (both losses btw). The other 21 games he was terrible. Two games is not a trend.Like mentioned above, he developed and became a good, not great shooter by the end of the year. Enough of a threat that you had to cover him.
You can't seriously think Europe is his limit can you?
I think he will likely be drafted in the NBA after his 3rd year at Purdue. Likely in the late first/early 2nd round.
