Boston have overcome the absence of leading scorer Jayson Tatum to improve their NBA-leading season record with a tight 106-104 win over Toronto.
"To win in the NBA is hard enough, to win on the road down a bunch of guys is hard to do," Brown said.
"You don't want to take it for granted, but we definitely have enough on this team, enough in this locker room, to win games whoever is on the floor."
A potential NBA MVP candidate, Tatum sat out because of a sore left wrist. He's averaging 31.2 points, the third-highest total in the league, and a career-high 8.5 rebounds.
The 21-year-old Mobley finished 19 of 27 from the field and had his top scoring performance as a pro without making a free throw or three-pointer. He added nine rebounds.
"That's exactly what we want to see from (number) 4," Garland said, referring to Mobley's jersey.
"Him being aggressive. Him just finding his pocket and doing what he does best. I would love to see that every night."
Mobley is only the fourth player since 1979, when the three-point line was adopted, to score at least 38 points without making a free throw or triple. Hakeem Olajuwon, Alex English (twice) and George Gervin are the others.
Jrue Holiday scored 28 and Bobby Portis Jr. added 23 for Milwaukee, who played their fifth straight game without two-time MVP Antetokounmpo (knee).
The Bucks remain third in the Eastern Conference with a 29-17 record while the Cavs (29-19) stay fifth.
Philadelphia (29-16) are second after their 129-127 triumph over the Kings in Sacramento.
There were also wins for Washington, Charlotte and Minnesota.
