I'm not that worried too.. If we can play like we have recently come Playoff time we have a fair chance against ANY Team.
Also the Hawks while playing good Team defense have no one who even remotley can guard Lebron 1vs1 They Have no Marion,Leonard,Green etc. Caroll and Thabo are solid defenders but none of them Is Tall/Strong enough to guard Lebron.
Also If Kyrie keeps up his trend of shutting down opposing PGs the Teauge/Schröder Rotation isnt that scary anmore.
The Horford/Milshap Dou is Dangerous though.. They could draw Mozgov out of the Paint.
