I've been expecting something like this to happen for years.
There is history behind this, from like 15 years back.
That story that Diaz told on some podcast within the last couple years about Jackson talking shit to some girl that Diaz liked is almost the same way I remember Diaz telling me the very same story within a day/week or two of it actually happening, a long time ago.
I've always wondered why Diaz never eventually stepped to Jackson as he grew into a world class fighter. If what Diaz just did in that video seems hasty, he had good historical reason to escalate things quickly there.
