Lines don't move because of RB's
Funny enough I was going to argue with you but I did some research and I learned today. Article is a few years old but is a good read.
Essentially, at most Nick Chubb could have moved the line by 2 points.
One of the biggest stories in the NFL last summer was a contract holdout. As the Dallas Cowboys labored through training camp in the Southern California heat, star running back Ezekiel Elliott lounged on a beach in Mexico and tested his worth.

After consulting two other Las Vegas oddsmakers, Andrews assigned point values to the league’s top running backs.
“We had trouble finding many guys who are worth more than a point,” Andrews said.
Only three running backs — Elliott, Carolina’s Christian McCaffrey and Tennessee’s Derrick Henry — are worth two points each to the betting line, Andrews said, and the New York Giants’ Saquon Barkley has a line value of one point. It’s not much, and that’s essentially the entire list of difference-making runners.
Andrews assigned values of a half-point to Cincinnati’s Joe Mixon, Green Bay’s Aaron Jones, Las Vegas’ Josh Jacobs and Minnesota’s Dalvin Cook, but those are insignificant adjustments considering NFL lines move a half-point all the time.
RUNNERS FOR THE MONEY
South Point sportsbook director Chris Andrews rates the NFL’s most valuable running backs and their worth to the point spread:
Ezekiel Elliott, Cowboys 2 points
Derrick Henry, Titans 2 points
Christian McCaffrey, Panthers 2 points
Saquon Barkey, Giants 1 point
Dalvin Cook, Vikings 1/2 point
Josh Jacobs, Raiders 1/2 point
Aaron Jones, Packers 1/2 point
Joe Mixon, Bengals 1/2 point
Andrews said his numbers are simply starting points and cases can be made that Elliott, Henry and McCaffrey could be worth slightly more than two points to the line in some situations, and Barkley might be worth a little more than a point.
