A guy nobody talks about, yet keeps showing up in these practice vids is RS freshman walk on Zach Simpson. He's about 6'2", 290. I think he was a preferred walkon. I am just wondering if he is somebody who will end up on scholarship and contribute significantly at some point. He wouldn't be the first center walk on at PSU to do so. Zach is from Holidaysburg and was a HS standout.
