7. Mike Iavaroni
The Grizzlies weren’t terrible in 2007. They had decent players on their rosters like Rudy Gay, Mike Conley, and an up-and-coming Pau Gasol. But then Iavaroni came and ran the franchise into the ground. Memphis had the makings of being a young and exciting team. Iavaroni saw it differently.

He remained in charge for less than two horrible seasons. First of all, he led them to a 20-62 finish in 2007-08. That’s just horrific. Imagine playing for a team that loses multiple times a week. It’s relentlessly draining and depressing. He then followed it up with an 11-30 start to the next season. At least he was consistent.
