Cardinals general manager Steve Keim and head coach Bruce Arians both had nice things to say about third-year running back Ryan Williams on Thursday. Speaking from the NFL combine, Arians made no qualms about Williams' athletic ability, adding he needs to stay healthy. That's been a problem for Williams after he tore a patella tendon and missed his entire rookie year, then had shoulder surgery that wiped out a huge portion of his second season. Keim was especially optimistic about Williams. "He’s a guy that, watching film with Bruce, because he got injured early in the season, you forgot the type of run skills Ryan had," Keim said according to the official team's website. "We watched him against Philadelphia, we watched him against New England, his lateral quickness, his natural run skills, his avoid-ability is something he brings to the table. Plus he’s a three-down back. We’re expecting big things out of Ryan moving forward."
