The last time the San Francisco 49ers had a rookie win NFL Defensive rookie of the Year honors was back in 2007. That player was none other than five-time first-team All-Pro linebacker, Patrick Willis. A stellar rookie campaign, Willis led the NFL in tackles, racking up 174, leaving little doubt in voter’s minds as to who the cream of the crop was during that time.
Fast forward to today, and the Niners may strike gold 12 years later, with the rookie addition of EDGE Nick Bosa. The Ohio State product has been living in the backfield through the first three games.
