“All he does is catch touchdowns.” That’s the line that Buddy Ryan used about Cris Carter before cutting the wide receiver. Carter got the message, and turned around his career into a Hall of Fame worthy one. With Carter, he had some issues with partying. I have no idea about Michael Roberts in that regard, but there are certainly some similarities in their play styles.
Both would be considered great athletes at a small school, but neither blows an NFL scout away with speed and agility. Both have good size for their position, and their best attribute is their hands.
