It's not just because of the acquisition of LeBron James and Chris Bosh either. It has more to do with the constant adjustments that are being made in order to get the best out of the team because it turns out there's a lot more to winning an NBA title than putting a few great players together and then telling them to go win some games against teams with established chemistry and systems.
What the Heat did to make themselves into a championship team was to utilize the physical assets they were stacked with, especially LeBron James. As gifted and as talented as James was before the 2011-12 season, we hardly saw what LeBron was truly capable of. Rather than having him run isolation plays and pounding the ball at the top of the perimeter, the Heat made it an issue to have James play other positions as well.
Thus why you have seen James guard the likes of David West and Pau Gasol: Because the Heat are making James utilize his physical attributes more than he has ever had to. Because the Heat are getting this out of James, they've been utilizing a positionless lineup that has made them one of the league's most unique teams.
Outside of James playing multiple positions, we have also see Shane Battier defend multiple positions, Chris Bosh playing at the four and five and even Dwyane Wade playing as large as the three. Due to the positive results of the positionless lineup, the Heat have continued to use it and have created a small-ball lineup out of it as well.
With the positionless lineup set to move on into next season, we take a look at five championship contenders who can run with the Heat and their lineup of stars who can play multiple positions when asked.
