In 2020, Justin Herbert became the first rookie QB to throw for over 4,000 yards and 25 TDs. He broke the NFL rookie record for TD passes and completions, in fact. As a result, Keenan Allen put together a more impressive season than any WR in our sample. Still, digging a little deeper, Allen did leave some meat on the bone. He finished as the WR7 in PPG despite seeing the second-most targets per game. He recorded a career-low of 9.9 yards per reception, as well. These minor inefficiencies can likely be chalked up to the growing pains of a rookie QB.
