Listen people, I don't wish to piss on your parade, but after doing my homework and reading experts' opinions from many available media sources, you really need to look in the mirror:
The Atlanta Hawks are coming into this series as the #1 in the East, having run a fantastic system throughout the season. Needless to say they have home court advantage. They have 4 all-stars on their roster (Horford, Millsap, Corver and Teague) and their pass-first team basketball style is a thing of beauty. This is masterminded by the reigning COY, Mike Budenholzer, who has learned everything about Pop's system and then some.
Cavs, on the other side, have lost their starting center early in the season, failed to incorporate KLove into their system (and then lost him to a freak injury, after being assaulted by an old lady named 'Kelly'), Irving is suffering from an injury that clearly limits his game and JR is out for the first two games. LeBron is getting old and will bail on the city (again) at the end of the year, as their basketball is ISO-dependent and their rookie coach cannot even count the number of TO he has.
Hate to break it to you, but this series has 'sweep' written all over it...
