Which line-up would win?

Both line-ups are about equal. Each player is very strong. I would say Lineup A would win. Steve Nash is a huge liability on defense. Chris Paul would school him. Team A could pick and roll all day. I also think that LeBron would own Carmelo. Carmelo isn't a very good defender. Team A has 3 unstoppable players (Paul, Wade, James) while Team B only has Kobe.
