The Warriors celebrated with their championship parade in Oakland, CA on Friday morning/afternoon. During the celebration, every Warriors player was interviewed and gave their input on this championship season. Of course, there’s celebrating, and then there’s being a little immature. As an NBA Champion and a member of a big brotherhood, Warriors forward Draymond Green showed his extreme immature on live television when he was interviewed by a Warriors’ sideline reporter.

Take a look for yourself and be the judge of it.

Even Warriors fans, when they get off of Cloud Nine, will admit this was a huge mistake and an issue of immaturity with Green.
