I broke this down on here a long time ago and people weren't trying to here me......He's been the underdog in most of his Finals.
Series Odds listed below:
-Against San Antonio in 2007: The Spurs were -500/Cavs were +400. Spurs were believed to have an 83 percent chance of winning the Series.
-Against The Mavs in 2011: The Heat were a -180 favorite/Dallas was +160. Heat were believed to have 64 percent chance of winning the Series.
(Note: Lebron's poor performance aside, I spent some time thinking about this recently and I do believe there were fundamental flaws in the design of the Heat's offense that played a key part in this result. For starters, the 2011 heat didn't have the spacing and perimeter shooting that later Heat teams had. Having Joel Anthony starting is a lot different from deciding to play Bosh at Center and Battier at the 4.)
-Against Oklahoma City in 2012: The Thunder are also -165 series Heat were +149. The Thunder were believed to have a 62 percent chance of winning the Series.
(Note: In retrospect, this may throw people off that OKC were such huge favorites given the gentleman's sweep Miami put on them but at the time OKC was seen as the better team. OKC had a better record, had home court and had the 2nd best offense in the league, coming off 4 straight wins against the Spurs, which looked like the prohibited favorites to win the Finals against a Heat team that recently struggled with Boston & Indiana and were experimenting with a small ball lineup with Battier at the 4. In the end it was Brooks refusal to adjust and go small [as well as OKC's youth] which ultimately doomed this series.)
-Against San Antonio in 2013: The Heat were -220/Spurs +190. The Heat were believed to have a 68 percent chance of winning the Series.
-Against San Antonio in 2014: The Spurs were -125 favorites over the Heat +105......Spurs were believed to have 55 percent chance at winning this series.
(Note: I know hindsight is 20/20 but I felt this way at the time. This Series was priced incorrectly. The odds could have easily been in the 70 to 80 percent range given the circumstances.
You had an older Miami Heat team who went to 4 straight NBA finals that found it difficult to execute their famous trapping scheme with Wade on bad knees, older role players, a burnt out Lebron James who was forced to carry the Heat all season long as they rested Dwyane Wade going against an all time great playoff scoring offense who effortlessly moved the ball and scored 119 points per 100 possessions. )
-Against Golden Sate in 2015: Warriors were -250/Cavs +210. Warriors were believed to have a 69% chance of winning the Series.
and now Golden State in 2016: Warriors are -225/Cavs are +185.........
