Preview of NBA Finals?

Great Game 4 between the Thunder and the Mavericks. I thought the Thunder were going for the kill, because they were up by fifteen points. Due to inexperience, Oklahoma City collapsed and gave away their lead to Dallas. The Mavs knew from experience that the game isn't over until it's over. There was still time to catch up. I think that OKC could use some of the experiences they learned here in Game 4 to not make the same mistakes again. They need to muster up some energy to keeping the lead late in games. I also like the Heat's energy against the Chicago Bulls. They went after loose balls, Dwyane Wade made two clutch blocks in overtime, and Lebron James played spectacular defense on Derrick Rose came the final seconds of the fourth quarter and overtime. I think the two better-played defenses and basketball teams overall, Miami and Dallas deserve to play in the NBA Finals. The Chicago Bulls and Oklahoma City Thunder were definitely lagging from inexperience, playing against the Heat and the Mavs respectively.
