After returning from his gun shots, B.Rob was given 1 week (Wk5) to warm up and be eased in to the offense.
From Week 6 through week 17 he averaged 1/.8/.18 + 18/14/92 = 10PPG
17 week pace: 302/1197/3 + 18/14/92 = 170 Fantasy Points.
Make no mistake, he was not a great RB for fantasy purposes.
But consider this, as far as workload goes.
302 carries would rank 3rd last year.
1197 rushing yards would rank 6th.
170 fantasy points would rank only 25th.
That's the nature of being a zero in the pass game, but his path to volume was very clear last year, and is arguably more clear this year. He's essentially a zero in the passing game, but there's a reason he's RB36 off the board.
If you feel there is any improvement in efficiency and/or TD rate, whether from health, Howell, or natural development, he has an extremely plausible path to RB2 numbers, even without any pass game improvements, and can be had as RB36, in the 8th/9th round.
If you arbitrarily cut the season in half, and isolate only weeks 10-17... his 17 game pace jumps to the following:
335/1403/2.5 + 19/12/128/2.5 or 194 Fantasy Points(RB21) 11.4PPG(RB29)
that would be the 3rd most carries and 4th most rushing yards in the league, for reference.
