I guess I'm in the minority for not having a problem with this fine. A few of the things that Suh has been penalized for and fined for in his first couple years were total BS, and perhaps some of the things he has done, such as this hit, or kicking Schaub in the balls, other players might have skated by on, but Suh has had done enough to earn his reputation (and not done enough to prove his haters wrong) that he won't get the benefit of the doubt on something like this. This would not be a $100K hit for anyone other than Suh, unfortunately.
I predict that the next hit that he gets penalized for this season will be something that a no-name player might have gotten away with, but there will be an equally large fine and/or suspension waiting for Suh as well.
It's too bad, because I like Suh, and his personality and demeanor were excellent during his time at NU, but his NFL on-field persona has gone the other way.
