A lot of people have been looking at Sterling Shephard or Golden Tate picking up the opportunities that used to go to Beckham.
I am not really seeing it that way. I think Golden Tate picks up a slice of what Beckham used to do and that Shephard stays pretty much the same as he has been.
Barkley had 120 targets as a rookie. It is hard for me to see him getting even more targets than this, although I suppose its possible.
In 2017 Odell Beckham only played in 4 games. It was Elis worst season since 2013 and Eli missed a game that year as well. In that situation Engram led the team in targets as a rookie,in the 15 games he played.
Eli actually had a bounce back year in 2018 where he threw the highest completion percentage for a season in his career 66% a big part of that is because of Barkley but Pat Shurmurs offense very favorable to QBs Bradford and Keenum as well.
Eli Manning the last 3 seasons
2016 16 598 attempts 377 completions 4027 yards 26 TD
2017 15 games 571 attempts 352 completions 3468 yards 19 TD ( pro rated for the missed game 609 attempts 375 completions 3699 yards 20 TD)
2018 16 games 576 attempts 380 completions 4299 yards 21 TD
3 year average 16 games 594 attempts 377 completions 4008 yards 22 TD
If Barley maintains his targets from last year that is 120
Shephard has averaged 6.8 targets per game over his first 3 seasons which over 16 is 110 targets
Engram has averaged 6.8 targets per game over the 26 games he has played in, but given that he only has about 1.5 seasons worth of games there is room for this number to go up in Beckhams absence.
Golden Tates numbers with the Lions and Eagles last season were similar to what he has done before in terms of yards per reception and catch rate. He just didn't get as many targets as he had been for the 3 seasons prior with the Lions. He will be 31 years old.
He had 113 targets last year which is a similar rate as Shephard and Engram.
So if it splits evenly like this that would be a total of 450 targets going to these 4 players and there is still another 150 targets remaining for throw aways and targeting other players. I don't really see Rhett Ellisons target rate going up

He did have 34 targets last year, however 12 of those were in games 11 and 12 where Engram was out. Once Engram returned to the line up his targets dissipated.
I think there is still substantial opportunity left for any of these 4 players to get more opportunity than what they have averaged in the absence of Beckham. It could be evenly distributed or maybe one of these four gets more than the others. They did still throw to Gallman 22 times and 3 other WR combined for 67 targets. So considering something similar will happen again although the majority of opportunity goes to the top 4 players there are about 50 or so targets left, although half of those will likely be throw aways.
Engram saw his efficiency stats improve on his rookie season. His catch rate improved to 70% from 55% his rookie year and his yards per target went up to 9 which is very good. That was only 6.3 as a rookie. If Engram maintains that with 110 targets over 16 games it would be 77 receptions 990 yards and some TD.
The TD upside with Eli has been poor as he only thew 21 TD last year and 19 the year before, but if Engram is healthy he should have a lot of receptions and yards.
