Because, really, before those comments the Chicago Bears had absolutely no reason to go out and play a football game.
Could they go out and try to avenge their second embarrassing defeat in three games? Sure, but that would be an obvious reason to play in the NFL's first Thursday night game since the season opener.
Could they go out and try to prove their defense is capable of stopping someone other than the Cleveland Browns? I suppose so, but again, that seems sort of cliche.
Luckily, boneheaded Vernon Davis went out and talked confidently about his team, and now these Bears are rejuvenated. Like a phoenix rising from the ashes, the loss to a team who plays their home games in Phoenix means the Chicago Bears will not tolerate the English language.
According to The Associated Press, Davis told reporters this past Tuesday the 49ers could dominate the Bears in the trenches.
"We can destroy their front," Davis said. "The guys up front, I think we can destroy them. I don't see anything spectacular about their front line."
Way to go, Vernon! You big doof! Look out for Tommie Harris, by the way. He punched Arizona's Deuce Lutui for being underneath him. You're lunch meat, pal!
When will these players learn that football teams could care less about winning games than winning battles in the media. It's not about getting scores, it's about settling them.
Look at what New England Patriots quarterback Tom Brady had to say about the Miami game after Dolphins linebacker Joey Porter spoke candidly to the media about his feelings about the Patriots.
"It's really motivating for our team throughout the week and into the game when you hear that kind of stuff," Brady said this past Monday while on The Dennis & Callahan Show on Boston radio station WEEI. "I think the guys take it to the heart, and the coaches take it to the heart."
Bonehead move, Joey Porter! The Patriots were ready to roll over and die, give your Dolphins an easy divisional win, and you ticked them off. I bet you are kicking yourself right now. Or maybe you're just doing your after-a-sack dance routine where you kick blades of grass. Either way, you're swinging your leg in a kicking motion at 3-5 because of your absurd cockiness.
Now it's Vernon Davis's turn to taste the bitterness that is eating your own words. When that 15th-ranked Bears defense steps on the field Thursday night, they're looking at one person: you.
You could have gone unnoticed, smart guy! You think the Bears had any idea before you brazenly mouthed off that you are the 49ers' leading receiver? Remember the part about NFL teams not caring about winning games? The Bears are one of those teams!
Your team might win the game by two touchdowns. Easily. But what is your stat line going to look like? Because that's what you have to live with. I would hate to be a 65-year-old Vernon Davis, talking about my career with my grandkids and having things get awkward when one of them asks about my two-catch, 13 yard performance on Nov. 12th, 2009.
"Your team scored so many points, Grandpa," they would say. "How come you didn't score? Huh, Grandpa? Why? Why?"
It's a horrifying series of images, Vernon, but you brought it on yourself. Remember that the next time you say something that hundreds of other people in the media have been thinking.
Good luck, buddy. You're going to need it.
