CLEVELAND — LeBron James returned from sickness, and the Cavaliers felt a whole lot better. Still not quite himself, James came back after missing one game with strep throat and scored 24 points, Kyrie Irving added 25 and Cleveland capped a solid February with a 102-95 win over the Milwaukee Bucks on Monday night. James sat out Saturday’s loss to Chicago — the Cavs fell to 0-4 this season without their superstar — and was listed as questionable before arriving at Quicken Loans Arena and getting in a workout.
