"It's too early to say," Fox said. "I haven't even had a shower yet, let alone look at the tape. We've definitely got to get better."
Will that be with Tebow under center? He certainly didn't look like he deserved to be there against the Lions.
Tebow, who was 18 of 39 for 179 yards and a touchdown, was erratic and off-target all day with some signature ugly-duck passes; he had the football stripped from his left hand and scooped up for a touchdown; he threw a pick-six that was returned 100 yards; and he was sacked seven times.
Still, at least one of Tebow's teammates has faith in him.
"Natural born leader. He's already proven that," rookie linebacker Von Miller said. "He's a great guy with great character.
"I feel like he can get it done. I'm a believer until the end."
That could've already come Sunday. But if you're a believer, too, and you still want Tebow, now would be a good time to start Tebowing.
