As I remember it, Shawn Tompkins died not too long after the Aldo fight, and Tompkins was a huge part of Mark's life both in training and outside the gym. He lost a trainer & coach who was pretty much like family.
This is true. I know a lot of guys at Adrenaline took his death pretty hard.
I don't think Stout or Hominick have been the same since, which is really too bad.
