My favourite argument is - "find me a replacement who is better".
No offense but it's really silly.
I just find it really hard to believe that people here are up to date on the talent pool for GMs.
I also find it hard to believe there is only 30 capable basketball GMs in the world.
I didn't know who half the GMs were before they became GMs. I still don't know who 1/2 of them are.
Pick a former college player who averaged 5ppg with a limited coaching career as a quiet assistant. That's the next great GM.
