Norv Turner is an old-school coach who doesn't need new math to help him count preseason snaps.
So you might want to count 'em first before asking the Vikings offensive coordinator if rookie quarterback Teddy Bridgewater needs more time with the first unit to better assess his battle with Matt Cassel.
"That is so overrated," Turner said. "You get an evaluation of a guy when he plays. The things that are going to happen to him with the seconds are the same exact things that are going to happen to him with the ones."
Then Turner did the math — literally — from Friday night's preseason opener against the Raiders.
"Teddy got a 10-play drive with the ones," he said. "He got as many snaps as Matt did with the ones."
Friday night, Cassel looked crisp as he completed five of six passes to four targets for 62 yards during a 10-play, 70-yard touchdown drive. Bridgewater went 1-for-2 for 13 yards while helping the first unit to a field goal. He also held the ball too long and too loosely on a strip sack in the red zone.
"Teddy showed all of the things that you need to be a quarterback in this league," Turner said.
The Vikings have not finalized their plans for the quarterbacks in Saturday's game against Arizona.
