"We're kind of preparing our team knowing we're not going to have those guys for the next three weeks," said Beattie, whose team is the only local reigning league champion and went the furthest in the playoffs last season with a second-round appearance in Division V. "I'm being optimistic for them.
"We're going ahead with what we have and, right now, we've got about nine guys on the roster because the other guys are all on basketball."
Of the non-basketball players, the top returners are outside hitter Nolan Jimbo, setter Kieran Mulroy and libero Alex Holden.
Jordy Manker and Gautam Tammewar will start the season as the Rebels' top middles until Smith and Norsworthy return and Beattie is looking for first-year varsity player Michael Ellis to step up at outside hitter early in the year.
"It's going to be difficult at the beginning, especially missing guys like Kenyatta and Jared, two big middles," Beattie said. "It's not like we're hoping they lose so they can get back faster. We want them to go as far as possible.
"It's concerning a little bit that by the time they get back, we're going to be pretty far into the season, but at the same time, it's a good thing for us, it's a good thing for the school and it's a good thing for those kids to go as far as possible."
Other than adjusting to the temporary loss of some starters, the Rebels must also find a way to offset the permanent loss of Edmund Chow, last year's starting outside hitter, whose experience as a libero made him a cornerstone of the Rebels' passing and defense.
