They picked an all-rookie team and Zach Frazier is the first-team center. Here's what the writer (Dane Brugler) had to say:
As good as (Jon) Alt and (Dominic) Puni have been, there is a strong case to be made that Frazier was the top first-year offensive lineman. Although his length and athleticism are more solid than exceptional, he already looks like a veteran with his strength at contact and ability to outmaneuver defenders. I think people get tired of hearing about wrestling backgrounds for offensive linemen, but with Frazier, you can clearly see how his skills on the mat translate to the NFL.
