Did you google it? There are a total of 9 football players with engineering majors. 5 of those 9 are Management, Science, and Engineering. I believe that degree isn't a weak degree, but it is more like a business degree than an engineering degree so I wouldn't count it as engineering. There are 16 with Science, Tech, and Society which is considered as a weak degree for Stanford. There are 51 with undeclared majors. BTW to answer your question, there are 4 current players who major in communication.
I do not mean to degrade Stanford as an academic institute. They rank higher than GT in Engineering and in Business. However, they do have places to hide athletes.
