That will be the case if he gets careless with his playing styles.
As long as he knows how to land then maybe it will take long before he feels the soreness.
Look at Lebron James. Just how much weight his feet carries everyday but up until now he doesn't have that bad injury with his legs.
It's about being healthy and with the right training on how to land.
LeBron mastered the art of durability. He knows how to position himself and used his body wisely so he could prevent himself from having a career ending injury.
I understand how hungry Morant is, most of the rookies is willing to give out their best, but dunking over a center is definitely unnecessary. I like the kid how he played the game and his a valuable piece of the Memphis team as well. It's just a waste of talent if he's trying to be a Vince Carter dunking on a 7 foot center every game.
My vote is also for Ja Morant here.
Give the guy credits. He changed the way Grizzlies play and they are 3 wins away from the Pelicans.
If he plays harder then he might really experience a playoff game even being just a rookie.
