Twitter can't believe McAdoo came into Game 4

Golden State Warriors head coach Steve Kerr wasn't bluffing when he said everyone was available for Game 4.
Trailing the Cleveland Cavaliers 22-21 with 3:01 left in the first quarter, Kerr opted to sub in seldom-used James Michael McAdoo for Harrison Barnes.
McAdoo played just 19 minutes during the playoffs and hadn't appeared in a game since May 7. His subbing on Friday resulted in Twitter going into a frenzy when he hit the court.
McAdoo???

James Michael McAdoo probably had to check to see if had put his game shorts on. #NBAFinals

Warriors don't appear as interested in rebounding ... So Kerr turns to McADOO????

James Michael McAdoo on the court. Security hasn’t removed him yet.

Ty Lue needs to check the lineup card! Was McAdoo listed as active?

McAdoo? Are you kidding me???? Is Festus dead?

McAdoo would score two points on his only shot in three minutes before Kerr subbed him out.
