I don't think Robertson was better than Anzalone, but if he was, the difference was insignificant. I saw Anzalone making very good plays in his 3.5 games last year, and that was as a rookie. I think the difference is that if Anzalone can play at a comparable or near comparable level now, then it is expected that he will be able to play at a much higher level after he gets more experience. Robertson is a very solid LB, but Anzalone is good now, and potentially great.
