Yeah, 38%/83% are really encouraging numbers re: his shooting ability in general. I know his 3PT stroke has been a minor question, but 83% FTs probably indicates that the 38% isn't a fluke.
I wonder how we should expect his offense to change, if at all, from having a PF defend him in college. The optimist in me wants to believe it could result in more threes (big guys less used to guarding perimeter, slower to close out), fewer midranges (less tempted to just shoot over smaller guys who cut him off after a dribble or two), and more attacks to the rim (easier to get a step on bigger/slower defenders), which should also lead to more FTs.
I would also hope/assume that K learned things from Jabarmageddon, and realizes that letting a Jabari float around on defense and take fadeaway 19-footers leads to shitty results. Tatum is also a better athlete and will have Giles as the back-line guy to rotate over to protect the rim, whereas Jabari pretty much had all that responsibility (and shitty perimeter defender teammates). Maybe there's hope.
