It you're looking for a pure example of "transitive property" in sports, you'll rarely find it. Though it does exist.
BUT... there is some validity in looking at comparative scores in a broad sense. And in this case... the fact that Toledo can put up 50 on CMU does say something. Though it's something we already knew...Iowa's offense is predictable and anemic.
Actually the offense had about 440 total yds in that game I believe? It was all the other bonehead stuff against a BAD team that make you sick. They had 100 yds of penalties and obviously some miscues on defense late in the game... not to mention a bad time for a onside kick flub. But, yes Iowa's offense is predictable in the sense that the passing game is not very explosive at the moment. They should have probably put up 50 against CMU. Perhaps we should never play a directional Michigan school is the real lesson here.
