"We'll see what else we can do. It's hard to say, 'this group, this group.' It's 11 guys."
Gase said the rushing, passing and pass protection gameplans, and which back is best suited for that specific matchup, must be taken into account when deciding about backfield time.
Also, Williams remains a core special teams player, which saps some of his available energy from scrimmage.
"There's a lot of things that go on with this," Gase said, "and trying to focus on one group is hard because it's a huge puzzle, and you're trying to put it together during the week."
Still, it's a safe bet that Drake and Williams will again share backfield duties Monday against the Panthers in Carolina.
After all, consider the knee-jerk, overreaction to their one-game productivity:
If Drake and Williams continue to average 165 yards from scrimmage, such as they did last week, they'll combine for 1,485 yards from scrimmage in the final nine games of the season. Ajayi produced 1,423 yards from scrimmage in 15 games last season.
It's an extreme projection, of course.
But Drake and Williams combined for 28 touches from scrimmage against Oakland, so it's not implausible to think they could fit snugly into the revamped offense.
Gase seems to like what he's seen from Drake and Williams as ball carriers, where they combined for 83 yards rushing on 16 carries.
