SI.com's Don Banks had the most thorough article on the Pro Day. He included many positive quotes from NFL sources, but also added this nugget which complemented Ryan at the expense of his teammates:
"Those Boston College receivers that he was throwing to, there's not a lot of talent there," he said. "It tells me that Matt Ryan must be a pretty impressive leader, a pretty impressive kid to have won 11 games this year with some mediocre talent around him. And that's taking into account those receivers and those linemen. They weren't much. To win 11 games in the ACC, which is a pretty good league, he must be a pretty good kid and a pretty good quarterback."
NFL.com had the following videos: An overview on Ryan | Ryan talks with Mayock | Mayock on Ryan and Cherilus
The Giants were one of the teams checking out Cherilus. Former BC offensive line coach, current BC Dad and current Carolina Panthers coach Dave Magazu was on the Heights to see Gos. (It was also a nice excuse to see his son Dom.)
Boston.com also had a short video of the day.
This clip has nothing to do with the draft, but I just came across it tonight in a search.
