1. Starters to play more: Coach Mike Zimmer said quarterback Matt Cassel "has a chance" to play the entire first half on Saturday night, which would suggest the Vikings plan to give their first-team offense much more playing time than they saw last Friday against Oakland. Zimmer said this week he's never placed as much importance on the third preseason game as many seem to do, so it's possible the Vikings treat this week's game as more of a dress rehearsal than next Saturday's game against Kansas City. Adrian Peterson still won't play, but if Cassel -- who seems like the favorite to win the Vikings' quarterback job -- gets two quarters of work with the first-team offense, we'll get a good sense of how he's handling offensive coordinator Norv Turner's scheme against one of the league's best defenses.
2. Safety dance: The Vikings are still trying to sort out a crowded competition for the safety spot opposite Harrison Smith, and Zimmer said he wants to take a long look at four veterans on Saturday night: Chris Crocker, Andrew Sendejo, Jamarca Sanford and Kurt Coleman. With Robert Blanton still out because of a hamstring injury, and rookie Antone Exum having played 60 snaps last week, it stands to reason the Vikings will use the four safeties for much of the night on Saturday. It's hard to envision a scenario where all four veterans are on the roster, and Zimmer said he's hoping Saturday's game will help the Vikings establish a pecking order at the position. That pecking order could have some important consequences for a number of players.
3. Cleaning up pass protection: Zimmer wasn't happy with the Vikings' pass protection last week, after the Raiders sacked the Vikings' quarterbacks six times and Teddy Bridgewater nearly lost a fumble deep in Raiders territory. The Vikings spent plenty of time focusing on protection schemes this week in practice, and though some of the blitz pickup work from their running backs looked better, the linemen were responsible for many of the sacks anyway -- especially the three that came late in the game on Christian Ponder. Particularly from younger players like David Yankey and Antonio Richardson, the Vikings will be looking for better results this week.
