The short answers are that nobody can take DeSean Jackson’s place and the offense will have to figure out how to move the chains the same way the vast majority of the teams in the league do. Very few NFL teams have a receiver with Jackson’s sheer speed and ability to run under almost anything a quarterback throws up there.
The Redskins didn’t have one in 2013. Jackson was an Eagle that year. The Redskins relied on Pierre Garçon to move the football through the air. Quarterbacks Robert Griffin III and Kirk Cousins targeted Garçon a league leading 181 times. They attempted a combined 611 passes so nearly one in every three throws was in Garçon’s direction.
And the receiver came through with 113 receptions, a total that both led the league and set a team record for catches in a single season. The Redskins did not have a top-notch offense doing things this way but they did rank ninth in total yards and the Garçon-centric passing attack kept defenses honest enough to for the team to rank fifth in rushing yards. It was a miserable 3-13 seasons but a shaky defense, awful special teams, and general team dysfunction contributed more to the mess than the offense did.
The piece went on to say there is no reason why this plan can’t work again during Jackson’s temporary absence. With Jackson missing all but a few snaps of the Dolphins game, Garçon was targeted eight times, catching six. Four catches were good for first downs and a fifth reception that should have resulted in a first down was nullified by a highly questionable offensive pass interference penalty.
