Debate: Preseason Week 3 spotlight
Speaking at his usual day-after news conference Friday, Whisenhunt said he would think about it over the weekend.
"I'm sure I'll get asked that question again," he said. "The next time I think maybe I'll have a little more information."
Kolb saw more extensive action and was 17-of-22 passing for 156 yards, including his first touchdown pass of the preseason. But he was intercepted twice, with one of them returned for a touchdown.
"We've still got some practice days left," Whisenhunt said. "Since we're not game planning, we've still got an opportunity to do some competitive practices with our defense so you get a chance to assess their play."
