Washington Wizards forward Paul Pierce is adamant that his side need to improve despite their comeback win over the Miami Heat.

The Wizards won for the sixth game on the spin as they rallied in the fourth quarter to secure a 105-103 victory over the Heat, in which Pierce netted 14 points.

"We got to build ourselves on great habits," Pierce told the Washington Post. "Tonight I wasn't happy with the defense, especially against a team struggling to score 100 points.

"We allowed them to shoot too high of a percentage. So them aren't the habits we want to have throughout the course [of the season]."

The Wizards are now 19-6 in their season at the top of the Southeast division in the Eastern Conference.
