MINNEAPOLIS -- For a while there, it looked like Minnesota was going to botch up another big game. (Could still happen, but stay with us here for a minute.)
During the first quarter and a half, the Vikings wiped out two sacks because of encroachment. Nickelback Benny Sapp extended a Chicago drive with a foolish personal foul. Special teams cover man David Herron unnecessarily slid into the end zone while trying to down a punt at the one-yard line, causing a touchback.
But as we sit here at halftime, it is the Bears who seem to be melting down. Cornerback Charles Tillman inexplicably left Vikings receiver Bernard Berrian alone on the sideline for what turned out to be a 99-yard scoring pass. On the next possession, Tillman horse-collared Berrian at the Bears' 36-yard line, putting the Vikings in position for another touchdown as the first half closed with the Vikes up, 17-7.
The Bears can calm things down if they can grab a score early in the third quarter. The first half proved that things can change in a hurry.
