From the Vikings perspective, that may not be such a good thing. In the four games that Locker started, the Titans struggled badly on both sides of the ball. When Tennessee loses, it loses big. Their three losses have come by scores of 34-13, 38-10 and 38-14. Even in their lone win, they needed a punt return and kickoff return for touchdowns to beat Detroit. How many teams can say that? Oh, wait.
The problems have come early and will likely be Priority One for Hasselbeck to avoid. The Titans have been outscored 41-13 in the first quarter. On average, they trail 10-3 after one quarter and find themselves in a bind. To complicate matters, that scenario repeats itself in the second half, which can lay blame on the doorstep of the coaching staff.
Halftime is typically where good coaches shine. They make adjustments as to what worked and what didn't in the first half and make accordant changes. The Titans have been outscored 35-14 in the third quarter, which typically turns one of their halftime deficits into second-half desperation.
When asked if the Vikings approach would be different with Hasselbeck at quarterback as opposed to Locker, defensive tackle Letroy Guion said a veteran quarterback is a double-edged sword.
"We don't change up too much of what we do when it comes to quarterbacks," Guion said. "But the one thing about a guy like Hasselbeck is that he gets the ball out so fast you don't have a lot of time to get to him. Younger guys read their progressions like they're taught. That takes time and gives us time to get to him. Hasselbeck has been around long enough that, whether he's got his play or not, he's getting rid of the ball quick. It's tougher to get to guys like that because there isn't much they haven't seen and they get the ball out in a hurry."
In most situations, seeing the backup quarterback starting against you would be a good thing. In this instance? Not so much.
