Every day On most days, our Vikings reporters walk you through what's happening that day.

Remember when the Vikings arrived in the Twin Cities a few months ago for the start of the offseason working program and Greg Jennings said Norv Turner's offense was making his head spin? He gave the juicy sound bite, but he wasn't the only one feeling overwhelmed by the new offense. After all, the philosophy, the scheme and even the terminology are completely different.

Fast forward to today, the last day in July. The Vikings are now on their fourth time through the installation of Turner's offense, according to first-string quarterback Matt Cassel, and the offensive players -- and most importantly the quarterbacks -- have gradually gotten it down.

"Each and every day we're working hard to continue learning the nuances of the offense, some checks, and also trying to see it through Coach Turner's eyes," Cassel said Sunday night.

Cassel and fellow veteran Christian Ponder got an early advantage over first-round pick Teddy Bridgewater, who didn't join the team until May. Those guys were in the building and in the offense a month earlier. But Bridgewater has proved to be quick learner, putting him in this battle with Cassel.

"It's a huge difference compared to where things were before," Bridgewater said. "For me, I'm a step ahead from when I first started learning the playbook."

Some heads are surely still spinning. But it has looked like these two QBs have theirs on straight.

TODAY'S VIKINGS SCHEDULE

SOMETHING TO THINK ABOUT

The Vikings allowed 37 passing touchdowns last season, tied for second-most in NFL history, according to Pro Football Reference. You would think with the explosion of NFL passing attacks that the dubious record would be held by a recent team, but it was actually the 1969 St. Louis Rams who allowed 38 passing touchdowns -- and that was in 14 games. The 1981 Baltimore Colts and 1961 Washington Redskins also allowed 37 in one season. Obviously, the Vikings need to be better in 2014, but the good news is Mike Zimmer's Bengals ranked 11th in 2013 with 22 allowed.
