I was unable to watch (thanksgiving stuff) but heres the video:
NFL.com news: Lions DT Suh ejected for unsportsmanlike conduct vs. Packers
In the first angle i thought it was unintentional, but the in the second angle you can see that Sue really wanted to kick or stomp him or at him. I liked Sue a lot up until this point, this is the kind of stuff Goodell needs to come down hard on. I hope he gets a massive fine and suspension.
Also if not Sue's selfish action, GB would have been held to 3 and Detroit would have only been down by 10, with almost 2 quarters remaining. Sue put himself above his teammates and got himself kicked out of the game and turned a defensive hold for a FG into an opportunity for GB to get a TD. Detroit lost a very important game and will now have a harder time securing a wild card spot. His actions were as selfish and unsportsmanlike like as it gets.
