Lester has made an immediate impact since he transferred from St. Albans after football season.
"He has helped tremendously," Duncan said of Lester, who is Sherman's second-leading rebounder at seven boards per game. "One kid coming in can make a major impact in Single-A. He is a hard worker. He listens. He is very coachable. The kids love him."
And they love each other.
"Everybody is getting along, and that is one of the reasons we are where we are right now," Duncan said. "They don't fight and argue all of the time."
Duncan also has a deep bench, with as many as six reserves receiving playing time. They are senior center Duncan Breeden, junior swingman Tait Pauley, sophomore guard Adam Pauley, sophomore swingman Corey Smith, freshman swingman Blake Nelson and freshman guard Tyler Stewart.
"We have been playing 10 or 11," Duncan said.
Duncan thinks Harrah, Lowe, Pauley and Smith can help the Tide compete at the highest level the next two seasons if they are willing to work.
"I think next year we are going to be even better than we are this year because of the playing time these young kids are going to get," Duncan said. "That sophomore class is a bunch of great athletes. If they work, we have a chance to be special. If they don't work, we won't. I think we will be able to be pretty good the next couple of years."
How well Sherman does the rest of this season will depend on its defense.
"When we play defense like we are supposed to, we can compete with anybody," Duncan said. "When we don't, we get beat by 20 or 30. We are 10 games in and have 12 more to go before the postseason. Our goal is to be a very good defensive team before the end of the year."
