The PG who can’t play defense myth

In the NBA these days fans always say PG cant play defense and are not worth it. Unless you happen to be 6’7 and play the point.

Now i really want to know if that really is the case then why does the NBA even draft 6’2 and under guards?

It must be that the so called defense liability is not as much as people make it out to be. Specially when teams play good defense.

Sometimes i believe people just use that narrative to criticize a player based on something the media created. Again if the player was that bad at defense then they would not be drafted specifically as high as some of these guys like Trae Young.

I dont even know why i care about this lol but i am serious like to me if it was a big issue all teams would have big guards already.
