2 roughing the passer, 3 times steelers dove on bengals after whistle was blown, no flag, close to 10 clear holds if not more (I know they're gonna miss some, but all of em?) , I mean how many bengals DL are gonna get tackled before its called, also an illegal formation on a td pass, if it wasn't that's an awful lot of leeway on being on the line of scrimmage (almost a full yard off looked like), and the defensive p.i. called on Cincinnati was atrocious, A. Brown at goal line, ball ob out of back of endzone (Clearly uncatchable), should've been 5 yds for holding if anything at all, but the fact they only flagged Pittsburgh once the entire game in ludicrous in itself, i mean what NFL team plays a whole game a commits 1 penalty, seriously. Also, I did see a few holds by Cincinnati not called, but not nearly as many as I saw not  called against Pittsburgh.
