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.
I'm not sure about Steins injury recovery, this may be somewhat of a factor. Personally, I think he got shoved around a lot. I like the kid, he just really didn't have a very good career. His motor is questionable. Maybe I am way off base though. I don't know for sure, but I think Bo's scheme can be really tough for defensive lineman to really put up GAUDY numbers as you say. So maybe some of these guys are better than some might think?
I hate when people compare other DL's careers to Ndamukong Suh's career though. Those are expectations nobody is going to meet. If people were expecting Steinkuhler to be like Suh, well then the bar was already set WAY too high from the get go. Now, would guys like Crick and Steinkuhler, maybe even Eric Martin have been better in McBrides scheme? Yep, probably.
