I doubt Morant would be as successful as MJ in said defenses, given Morant's much poorer outside paint percentages and allowing more physical lane defense is worse for the shorter guys driving.
Takeaway to that being a valid criticism now of Morant. He would definitely need a better outside shot to develop should the lanes close. I've already given a recent example series where that very thing just happened. Trapped and lanes close off, 21ppg averaged for Morant. I'm sure he'd have no problem getting 20ppg given the examples. However, there is valid skepticism. The haziness on the subject comes from his poor midrange.
You don't need Pistons level, championship physical defense, just T-Wolves level of dealing with it which is entirely feasible.
Dumars' accolades that year are stellar for anyone, let alone a guard. Putting down that high level of defensive play, coupled with a Finals MVP and 'ship on the same year, to prop up Morant's otherwise early exits is foolish.
Grizz record without Morant was pretty good, but I'm not gonna hold it against Morant.
I could see more people taking Klay because he's a far better shooter.
