Not sure how you are calculating this but Love is shooting 44% from 2 on 72% of his attempts and 39% from 3 on 28% of his attempts (which is the equivalent of 58.5% from 2) for a blended FG % of 48% which is still well below Blake's 51%.
Ok I looked up true shooting and see it includes free throws. Giving free throws the same weight as field goals is very misleading because the player is not being guarded. If you included them at 25% value maybe, full value, meaningless.
FTs are not given the same weight as a FG attempt in TS%.
