Sorry guys, but for me personally, it's just ridiculous to turn on a top-5 (definitely, even better by my evaluation) coach in the league instantly, after a couple of hard-nosed defeats against such a good team Heat are. Not even speaking about candidates you can replace him with, I think a lot of people need to chill down and look at the bigger picture: Celtics did beat the Raptors without Hayward, now battling another tough opponent in a very-very close games. Stevens is not a problem, it's just a process of growth for a young team we have.
P.S. This series is not lost, guys, by any means. And I assess reports of item-throwing in the locker-room as a good sign of guys really wanting to be better. Rockets or LAK fans would've loved these kind of news recently.
