Philadelphia Eagles fans should be cautiously optimistic about Chip Kelly's arrival as the team's new head coach, because history shows us that college coaches fail in the NFL more than they succeed.
I'm a huge fan of Kelly's work at Oregon, and I'm of the opinion that his style of coaching and his scheme on offense will translate well to the pros. That said, the Nick Sabans and Lou Holtzs of the world have shown us that what works in theory doesn't always work well in practice.
As a quick lesson in history, we've compiled a list of 10 notable college coaches who made the jump to the NFL. Judging by their records and impact on the professional ranks, we'll assign grades to each one.
