4. Keenan Allen aids in the development of Justin Herbert
Allen was once the mid-round prospect that the Chargers helped bring along to where he is today. Now, the team needs him to help in the process of developing Herbert. The former Oregon Duck is unlikely to get into action earlier in the season, but Allen will be a necessary component once he does.
Having an elite, veteran receiver has dramatically helped some of the young quarterbacks around the league in recent years. Larry Fitzgerald aided the development of Kyler Murray and DeAndre Hopkins helped Deshaun Watson big time.
While not a veteran receiver, Tyreek Hill’s speed was a huge part in opening up Kansas City’s offense in 2018 so Patrick Mahomes could be as effective as he was. Oh, also he had Travis Kelce.
Timing is one of the aspects that I believe Allen could really help with. Rivers and Allen developed perfect timing on many routes. He was almost always in the right spot at the right time. In addition to Herbert needing to learn NFL cadences, he also needs to learn NFL route trees as well as pro timing. In my mind, there’s not any other receiver in football who can assist in both of those departments more than Allen.
In general, it just seems like quarterback development ends up being much slower when a quarterback doesn’t have an elite target to throw too. Mitchell Trubisky and Daniel Jones have mostly played with mediocre receiving talent up to this point, generally speaking.
