The obvious followup question is when will No. 1 overall draft pick Jared Goff be ready to move up from third on the depth chart?
Fisher told NFL Network's Steve Wyche last week that the plan was for Goff to ascend to the backup role in Week 2, flipping with Sean Mannion.
That plan is not set in stone, however.
During Monday's press conference, Fisher said only that there is a chance Goff will advance enough to handle backup duties this week.
Until he surpasses Mannion, Goff won't be a candidate to see game action.
The conundrum for Fisher and his offensive coaches is that Keenum has thoroughly outplayed Goff, who struggled with pre-snap reads, post-snap reads and the overall speed of the NFL game during August.
The problems go beyond the quarterback in Los Angeles' offense.
If that predictably was a scheming issue, offensive coordinator Rob Boras will have to go back to the drawing board. If it was partially the result of Keenum's obvious physical limitations, there's a danger of rushing Goff into the starting lineup.
The Rams firmly believe their top draft pick will be a "great player" some day. It has been clear for five months, though, that he's going to need time to master his craft with more practice reps before he's ready to orchestrate an NFL offense.
