MANKATO, Minn. (AP) John David Booty felt different running onto the Metrodome turf for Friday's preseason game.

Seeing the big NFL logo at midfield was something Booty says he's dreamed about his whole life.

The rookie quarterback from Southern California enjoyed is NFL debut, despite a few mistakes.

Booty played nearly the entire second half of the Vikings' 34-17 loss to Seattle. At times, he showed the promise that made the Vikings draft him in the fifth round, completing 9 of 18 passes for 82 yards.

At other times, Booty looked like an unsure rookie, taking two sacks, losing a fumble and throwing an interception.

Coach Brad Childress says he thinks Booty struggled with the speed of the game, making quick decisions and trusting what he sees. But Childress says Booty will get back out on the field this year.
