The Los Angeles offensive line overhaul continues with Ragnow, who fits a need but also may be the best center prospect we’ve seen in years. He’s a dominant run blocker, creating holes at the first and second level, and he’s shown well against top SEC competition over the last three years. Before a season-ending (ankle) injury, Ragnow ranks as the nation’s top-graded center at 93.7 after leading the nation last year as well at 93.4.
