Big Three can make difference!
3 super-star players can win the league for you sometimes, as Warriors did with Chamberlain Arizin and Meschery in 1962, LAL tried with Bryant-O'Neal-Fisher in 2003, but they didn't.
LBJ Bosh and James in 2011 made 73.5% of Miami's points (yes, 73%), but you need something (someone) behind the stars, or your bound to crumble sometimes during the season, especially if your coach never taught you how to work for points: Spoelstra took the typical Pat Riley team in defence "no prisoner, it's us against the World", he started to put the team together working on defence, but this team didn't have an offensive identity. Spoelstra initially thought "We have the big three, we have flair, it will bury our problems", it didn't! Until he tried to do this, Miami performed inconsistently.
They worked on it, but in the end, those problems came out again. In the worst possible moment.
Game 6 talks for the rest:
Dallas has been more "team", with some great impact players (like in rugby of course) from the bench as Terry of course, Stevenson, also Brian Cardinal made a couple of awesome plays in game 6 (overall +/- it's +18, and he scored 3 pt!!).
43 points came from Dallas bench, only 20 from Heat ones, that means that when Nowitzki struggled with field goals (he started his 3rd period with 2/19...), there were some other guys who put the ball in!
