Last year he averaged 4.6 yards per carry which is not low.
His touches increased from an average of 10.5 per game over the first eight games to 19.125 per game over the final eight games.
His TDs increased from 0 over the first eight games to 6 over the final eight games.
His lost fumbles went from 2 over the first eight games to 0 over the final eight games.
He came in as the feature back and is the feature back and Buck Allen is the 3rd down receiving back.
Game scripts have impacted his touches so-far this year with a blowout win and a game where they got down quickly and went with the receiving back earlier and more often than expected last night.
He is going to get his, he's going to have big games and score but obviously game scripts effect his touches.
Go back and look at his last 10 games for YPC. His YPC was falling significantly over the course of the season in 2017

Since Week 8 of 2017 Alex Collins has gotten 148 carries for 543 yards, an average YPC of 3.67
One could argue he hasn't gotten the volume this year to turn his average around, and for that I would agree, but it's concerning to see a lot of sub 4.0 ypc on that list there, even with heavy volume.
Not ready to completely bail on this guy yet, but I'm not overly impressed so far.
