Wednesday's overtime win against the Kings was different from the Friday's overtime win against the Raptors. The Nets were up 17 in Sacramento, down 18 in Toronto. Vince Carter won one game, Devin Harris the other. Still, the two games--along with wins over Detroit and Atlanta--show the Nets have embraced a mental toughness this season. No one has embraced it more than Harris, who keeps pushing limits.
