Says Pro Football Focus:

Jackson was a bona fide fantasy star early in his career, topping 900 receiving yards seven times in his first nine seasons split between Philly and Washington, and putting up at least 4.3 yards after the catch per reception every year. Times weren’t as good in Tampa Bay, however, as Jackson totaled barely over 1,400 yards across two seasons with the Buccaneers and topped out at a lower YAC average than he ever put up before. Even at that, Jackson’s 2018 numbers are elevated by his 275 yards and 3 touchdowns in Weeks 1 and 2; the rest of the year, in 10 games, he totaled 499 yards, 1 touchdown, and only 1.7 yards after the catch per reception.

That’s always been Jackson’s game, though. He has been enough of a boom-or-bust player in his career that he’s become his own fantasy football archetype — he once went three full seasons (2014-2016) without a single game between 6 and 10 standard fantasy points. That trend tapered off a bit in Tampa Bay, but his upside still remains high.

Back in Philly, Jackson is at best the No. 3 man in the target pool, behind Zach Ertz and Alshon Jeffery, but he fills the outside-receiver role the team has lacked after Torrey Smith and Mike Wallace failed to fit the bill in recent seasons.

With a strong passing offense that also includes Dallas Goedert and if-he-sticks-around Nelson Agholor, the Eagles won’t need Jackson to be a target hog, but he can still put up the occasional big game. That makes him mostly an afterthought in redraft leagues, but for best ball purposes, Jackson is worth a late flyer.
