The Rams let Josh Reynolds walk and replaced him with Jackson. The move caps Van Jefferson's upside whenever Jackson is healthy. If being "injury-prone" is a thing, potential drafters should have serious questions about Jackson's ability to stay on the field. Since his age-30 season, Jackson has played 15, 14, 12, 3 and 5 games in the last five seasons. Rams HC Sean McVay was the OC in Washington from 2014-2016, when Jackson posted receiving lines of 56-1169-6 (in 15 games), 30-528-4 (in nine games) and 56-1005-4 (in 15 games). That last line was from his age-30 season, so it was several injuries ago. A game-changer when healthy, Jackson is worthy of a late-round pick in best ball formats but is likely to hit the waiver wire in redraft leagues.
