Here is Mike Clays team projection for the Bears
He has the Bears throwing the ball 534 times and running the ball 410 times including 67 rushing attempts for Tribisky. with 34 sacks this is 978 total plays. Down 35 total plays compared to last year. Tougher schedule could account for that.
Clay has Mike Davis with 52 rushing attempts over the season, 5 targets 4 receptions. Maybe the rushing attempts for Davis here are a bit high?
He has David Montgomery with 215 rushing attempts 950 yards (4.4 ypc) 6 TD 47 targets 36 receptions (76% catch rate slightly above average for RB) 1 TD in PPR this is 204 points which is RB 25 in Clays projections.
He has Tarik Cohen with 76 rushing attempts 339 yards (4.4 ypc) 2 TD 78 targets 59 receptions (75% catch rate which is Cohens career catch rate so far) 570 yards 4 TD in PPR this is 184 points which is RB 29 in Clays projections.
I think I mostly agree with these numbers although I think the rushing attempts for Davis may be a bit high.
