There was going scoreless on 0-for-5 shooting in the season opener's first 2:41 before Jayson Tatum cracked the iceberg. Their next game is on Friday versus the Toronto Raptors.
"The challenge is to grow him and help us win the game", Brown said.
Brad Stevens always expects his players to step up when others are struggling, and while the Celtics' deep rosters makes it easier for them to do this, it also means asking players who would otherwise be starters elsewhere to play fewer minutes and take on reduced roles. Joel Embiid scored 30 points.
"I'm never afraid", Fultz said of shooting.
Before coming over to Beantown past year, Hayward spent seven seasons in Utah and has career averages of 15.6 points, 4.2 rebounds, and 3.4 assists.
Aron Baynes and Al Horford did an exceptional job on Embiid, drawing offensive fouls, fighting to keep him off his spots and, on plays like the one below, challenging his shots with enough physicality to keep him off balance but not enough to get called for a foul.
It will take a lot more than one made three-pointer for defenses to stop sagging off Fultz. However, how valuable is he with 2017 No. 1 overall pick Markelle Fultz receiving extended action?
"I try to coach him without the knowledge of his draft order", Brown said of Fultz.
Now I'm definitely not discounting Hayward's talent. "It's inevitable he will have ups and downs".
They shot a combined 6-for-26 for the game.
Just as they did in the conference semi-finals a year ago, Boston held firm against the young Philadelphia 76ers before pushing them aside with a dominant second half.
The curious case of Fultz's missing jumper continued against the Bulls when one of the more scrutinized players in the National Basketball Association managed to steal the spotlight from his more accomplished teammates with routine - yet highlight-reel worthy - baskets.
Simmons had 12 triple-doubles last season and became the first player in franchise history to accomplish the feat in a home opener.
Barkley's Celtics hate has apparently carried over into the 2018-19 season, given his postgame comments following their 105-87 victory over the Sixers Tuesday at T.D. Garden.
