I appreciate the work on projections here.
I think your rushing attempts for Cohen are too high. Targets are likely too high as well. 7 targets per game would be 112 targets over 16 games. Those are David Johnson or LTs best season in terms of targets. Seems like too much, even with considering the Bears lack of other receiving options.
For an end of season guess at his numbers I would expect something more like 70 rushing attempts and 80 targets. Maybe that is too low but with only one game to work from, it is hard for me to be more optimistic than that. I still expect Howard to be their primary RB. Theo RIddick did have 99 targets in 2015 and was averaging 6.7 targets per game last year before being injured. So if Cohen is going to be used in similar way, 100 targets certainly possible, I would just lean to something more conservative then this, until proven wrong. I would rather under project a unknown player than to over project for them.
80 targets is 5 targets per game, which is still a lot for a RB. Chris Thompson of Washington is another example of a COP receiving RB and the most targets he has had in a season is 62 (3.8 per game) Even Darren Sproles who is one of the best receiving RB in NFL history only had 100 targets twice. Otherwise he has had targets in the 70-90 range. I am really not comfortable with projecting that high of targets for Cohen based on the information I have right now.
The last time I looked at RB receiving averages, a RB averages 73% catch rate and about 7 yards per reception. Cohen may be better than average, but with no NFL sample size to base this on for him, I would just plug in average numbers there for now, until we have 3 or 4 weeks of data to work with and try to extrapolate from. FWIW I used average numbers for Kareem Hunt moving forward for much the same reason.
So 70 rushing attempts at 4.2 ypc is 294 rushing yards. 80 targets at 73% is 58 receptions at 7 ypc is 406 yards. That is 700 combined yards or 44 yards per game.
I dunno. Even being optimistic and giving Cohen 100 targets 73 receptions 511 yards receiving, he is still falling short of 1000 combined yards.
