MANKATO, Minn. -- A daily review of the hot topics coming out of Minnesota Vikings training camp:

• The Vikings' quarterbacks were more efficient on Saturday than they were in the team's first practice on Friday, though we didn't see Matt Cassel, Teddy Bridgewater and Christian Ponder take quite as many shots down the field. Cassel again took most of the first-team snaps, finishing the day 10-f0r-13 in 11-on-11 drills, while Bridgewater went 8-for-11 and Ponder was 6-for-7. Cassel had one pass broken up by Linval Joseph, who had also batted down a pass on Friday, but he did connect with Greg Jennings on a long throw that drew one of the day's biggest rounds of applause. Bridgewater and Adam Thielen, who seemed to click during the Vikings' OTAs and minicamp, were in sync again on Saturday. Three of Bridgewater's last four passes were targeted for Thielen, and the two connected on a long play-action pass late in practice. Bridgewater mostly worked with the Vikings' second team, and Ponder's snaps were with the third team.

• With Munnerlyn out, the Vikings tried several different players at the slot cornerback position; rookies Jabari Price and Kendall James got some work there, as did Shaun Prater. Price got some first-team snaps and handled himself well. He said he played the slot corner position as a junior at North Carolina before moving back outside as a senior, so as the Vikings try to identify players who can handle the job in the event Munnerlyn gets hurt, Price could make his case for a roster spot that way. "It's definitely a harder job, but you can't put it on the back burner," Price said. "Other teams get those fast receivers in on third down. It's definitely a change-up for corners, but it's something that's got to be done."

• Nearly a third of the Vikings' 24 completions in team drills went to running backs, and they put a particular emphasis on setting up screens for Adrian Peterson. Peterson caught one from Matt Cassel, did a masterful job of letting his blockers get out in front of him and raced down the left sideline for a big gain. By my count, Peterson was targeted with four passes, catching three. "There are times where he'll double-catch it a little bit, but most of the time, he's pretty darn good," Zimmer said. "People are afraid of his speed, which gives him some areas to go underneath or beat people to the perimeter. I think he'll be a good weapon. I think when I was in Atlanta (in 2007), he caught a (60)-yard swing pass (in his first NFL game) for a touchdown. Once he gets the ball in his hands, if it's in the open field, it's bad news." Zimmer was also impressed with Matt Asiata, who's making a strong case at the moment to be the No. 2 running back. "He's elusive," Zimmer said. "He's got a little bit of shift, a sneakiness about him the way he goes. He's been good."

• For the second day in a row, the Vikings used a nickel package with three safeties, and Zimmer said he also has a three-corner, one-safety base look that he'll unveil at some point. "We're introducing them, and we'll continue to add some," Zimmer said. "We'll get to some more exotic things, I guess you'd say, later on in camp."

• It seems like Norv Turner's offense will employ pulling guards more often than Bill Musgrave's scheme did; the Vikings had rookie David Yankey pulling on a number of plays. There will still be some zone blocking, but it doesn't seem like the Vikings will be as married to that style of offensive line play as they were with Musgrave.
