Haha, let's check LeBron's record then. In his 7 years career, his team record against 50 wins team, 1W5L. And 2 of 6 times they're the favorites. Kobe's team may not have beaten many 60+ win teams. But they beat 3 50-wins team in WC alone for 08 and 10 playoff run. And overall Lakers did it 10 times over the last 3 years. So Kobe does have 10+ times more success than LeBron in terms of beating good teams.
Melo's last basket was a shame. Nuggets trailing by 6 with time winding down. His team needed a 3 and a quick foul. But he had 48 points. What does he do? Instead of taking a lightly-contested 3-pointer, he drove to the basket for a guaranteed layup to get his 50.
