Allar carried the ball five times. Of those five, one was a sack, and one was on a 4th and 1. Of the remaining three, at least one was a case of the defense keying on the RB and leaving a substantial hole for the QB. Allar carried for 8 yards and converted on 3rd down. Of the remaining two, IIRC one was a blown play and the other was similar to the 8 yard gain in that the defense went after the RB and left a hole that Allar was able to exploit for a 5 yard gain..
At this point, many, if not most college offenses expect the QB to do some running. For perspective, Bryce Young currently leads Alabama in rushing yardage and is second on the team in carries with 12, the same number as Clifford. If we're going to give a back-up QB "meaningful" snaps, it seems reasonable that those snaps involve using the whole playbook, including the plays where the QB running is an option.
