They take 4-5 NBA guys just about every year.

Just off of the top of my head, here are the locks:

Lebron James
Kevin Durant
Russell Westbrook
Steph Curry
James Harden
Carmelo Anthony
Chris Paul
Dwyane Wade
Chris Bosh
Dwight Howard
Dirk Nowitzki
Vince Carter
Tony Parker
Pau Gasol
Kevin Love (he is the most borderline on this list, but his stats probably get him in today)

This list does not include guys that I believe will ultimately end up in the Hall like:

Klay Thompson
Draymond Green
Kyrie Irving
John Wall
Paul George
Jimmy Butler
Blake Griffin
Anthony Davis
Kawhi Leonard
Damian Lillard
Demar Derozan

It also doesn't include young phenoms many of whom will make it eventually, we just don't know which ones yet.

Karl Anthony-Towns
Giannis Antetokounmpo
Kristaps Porzingis
Nikola Jokic
Joel Embiid
Ben Simmons
Donovan Mitchell
Jamal Murray
Devin Booker
Myles Turner
Bradley Beal
Jayson Tatum....etc
