3.25 avg is more than enough to keep going with it. If you average between 3-4 yards, then you keep running those plays... Even 2 yards is 20% of the down, more than incompletions and the risks of forcing throws. At the end of the day, you don't abandon, you find a way to make it work. Abandoning is really only an option for... Burrow, Mahomes, Allen...?
Jordan Mason ran 6 times for 15 yards in the first three quarters against the Bears. Then 9 times for 56 in the 4th. You don't abandon the run. Jones had 8 attempts for 23 yards, 2.9 avg.
