Success and improvement breed confidence, a key to fending off frustration. Kevin Love has followed that formula and progressed to the point where his clutch contributions toward big wins are expected by the Minnesota Timberwolves. Love scored 12 of his 20 points in the fourth quarter, including a pair of free throws with 0.1 seconds left, to lift the Timberwolves to a 92-91 victory over the Philadelphia 76ers on Sunday night.
