What a great matchup. Two of the best (or two best) coaches in the league, against clearly the 2 best and most capable teams in the league that know how to come together to win.
Spurs in 6. They have a better bench and stronger interior, and matchup as good as anyone against the heat. I also believe they have a better ability to overcome foul trouble, and they are going to come into this matchup with a lot more hate and passion than last year. This is probably the biggest difference from last year's play, not to mention the further growth of their young players, particularly leonard.
Whichever team wins, it's going to become 'legend-fodder' for the primary story lines of the winning team.
