"Kevin love cant play D" is a huge misconception among the ignorant public, GO WATCH HIM PLAY FOR GODS SAKE. Hes not bad. He does things techniquely well when it comes to defense. Its like saying James Harden is bad defensively which everyone and their nans think, yeah Harden aint exactly great but to say he is terrible due to some youtube highlights is beyond stupid, Harden improved alot defensively this year compared to previous years, hes still got a long way to go but its defintely getting better.
Heres some things Kevin Love does well on defense; He squares up perfectly, he cuts off angles, good foot placement, using his height in a good way.
Heres a thing Love does poorly on defense; Takes plays off/leaves his man. He does this because his offense is prioritized. Its a strategic selection.
