Why the Miami Heat won't win the finals this year

The Miami Heat has three top ten stars in Dwyane Wade, Lebron James and Chris Bosh. Before the season began I admit the three of them playing together seemed interesting but now I'm not so sure about it. One of the biggest problems is the Center position. Zyrdunas Ilgauskas is only average and Erick Dampier doesn't really work well either. Miami likely doesn't have the cap to land Dwight Howard or entice him away from Orlando. The second reason and the biggest reason I feel that Miami won't win the NBA finals this year is because of Wade, Lebron and Bosh. While they are great players the problem is who takes the final shot in the last seconds of the game when the game is on the line. Lebron has a way of choking and Dwyane Wade the other night missed off of Lebron's miss. Here to me is the solution for the Heat give the ball to Dwyane Wade in the final seconds or another idea is to mix it up. One game let Wade take the final shot, the next game let James and another Bosh. If teams start figuring out this plan then switch it up to throw off opposing teams. Who do i think will be in the finals will either be The Boston Celtics or the Chicago Bulls in the east, the west it will be either the Lakers, Spurs or Mavericks. So if Miami Heat wants to win the finals in the last seconds they need to start playing as a team and each guy needs to stop trying to be a hero at the end and getting there own stats.
