Why would the Hawks be worried about a Montreal team that is GASSED right now? They have nothing left, they won't beat Philly who had an easy first round series.
Now onto Philly who is the 7 seed. They beat an overrated New Jersey team and a terrible Boston team that complete collapsed after being up 3-0.
Hawks beat an excellent Nashville team that has an excellent system, an excellent Vancouver team, and are on the verge of completely dismantling an elite San Jose Sharks team that beat in Detroit in 5.
So if after that explanation, you still don't get it, I would suggest going to bed, getting some sleep, and think about it again in the morning.
