SAN FRANCISCO -- Tight end Vernon Davis, one of Alex Smith's staunchest supporters, thrived Monday night behind the starting debut of quarterback Colin Kaepernick.
In the 49ers' 32-7 rout of the Chicago Bears, Davis caught six passes for 83 yards, including his first touchdown reception since a Week 3 loss at Minnesota. Davis had only nine catches for 101 yards over the 49ers' previous four games.
"Colin is the man," Davis said to open his postgame news conference. "He did a great job. I'm very proud of him. He stepped up today and did great things to help us win."
Davis declined to thrust himself into the debate as to who should start at quarterback going forward.
"That's up to the coaches," Davis said. "I can't choose sides. I'm here to support either one of them."
Davis' final catch, an 11-year reception in the fourth quarter, served as a strong endorsement of Kaepernick's skills.
"The ball he threw was one ball that Tom Brady throws," Davis said. "It was in the second window, right on the money. We've run that play many times and usually the tight end doesn't get the ball."
"Fifteen years ago, neither quarterback sits out," said Young, working field-side as an ESPN analyst. "It's different now, and for the better. They're probably on the cusp of feeling better and not quite there. ... Concussions are always hard (to diagnose). It's not a bad arm or bad knee."
Young's 49ers career ended in 1999 after he sustained a concussion on a sack against the Arizona Cardinals. As encouraged as Young is by the NFL's serious approach to concussions, he believes flaws exist in the post-concussion review, specifically the use of independent neurologists who are not familiar with the "football context" of players.
"Independent doctors don't want to take the risk. They have nothing to gain," Young said. —'Independent' sounds great but I don't think it's practical."
