I'm going to go against the grain and say that I am actually surprised that Steinkuhler didn't get invited.
It's a HUGE surprise that Steinkuhler didn't get an invite. Some fans got down on him because he didn't have the gaudy stats that Suh had. But he did what he was assigned to do: he clogged up the middle. Look at what happened to our run defense when he was out with injury. Remember the B1G CCG? The wheels fell off the wagon without him.
/I wonder if Baker still isn't fully recovered? Maybe that's why he isn't going to the combine.
