But, have the Big 10 hurt themselves by adding Rutgers?

This is the question that every conferences have to face. You have to look outside what school Presidents' wants. Academics have to be tossed out the window. A school bringing academics to the conference would not bring value when the school sucks at sports. Tulane, Rice, Buffalo, Rutgers, UConn and UMass right now suck in most sports. UMass' men's basketball and UConn's women's basketball are the exceptions. The question are these schools bring anything to the table? I say no. You have to look at schools that have been great at sports in the last 20 years that could bring value.

As we have seen, the P5 have fallen to teams not part of the P5, but they do bring competition and viewership to bring with them. I do not think people want to see sorry teams like Rutgers all the time, or UConn in football for that matter. As we have seen in the tournaments for men's basketball,we have seen the Dakota schools knock off P5 schools. North Dakota State knocked off Oklahoma in the round of 64 a few years ago.
