Is it just me or does it seem like the pittsburgh steelers have been getting cheated lately?

Over the last few weeks I have been watching the Steelers play. I have noticed the extreme amount of flags that have been thrown against the Steelers, and the officials have almost showed favoritism against the steelers opponent. It almost seems every time the Steelers make a play, a flag is thrown. Every time James Harrison even touches another player on the other team, there is a flag thrown or he is fined another 25,000. I find this whole entire deal absolutely disgusting. When the Steelers played Oakland a few weeks ago, I heard the whole entire crowd chanting , “Ref’s you suck,” all in unison. When they played Buffalo last week I basically saw the referees give the Bills that field-goal to tie that game at sixteen.
