Jefferson will replace and surpass Reynolds. Jackson's job is to open up the field and score tds whenever possible, something Reynolds didn't do very often.
Reynolds had 2 tds in 2020 and 1 td in 2019. 9 tds in in 4 years.
Everett had 1 td in 2020 and 2 in 2019. 8 tds in 4 years.
Good examples of the how the Rams' offense lacked playmaking and red zone capability. And, unfortunately, of players who didn't develop as hoped. (Oh wait.. it was Goff's fault.)
I think Jackson will surpass both those guys' totals for touchdowns last year, and sooner rather than later. Of course, that's not exactly a high benchmark to clear.
