Quick, before I drive over to University of Phoenix Stadium in Glendale:
1. How many blitzes will Vic Fangio call? He called one last week.
2. How many touches will Bruce Ellington get on offense? He got none last week.
3. If Vernon Davis plays, how fast will he be? Can the Cardinals cover him with a linebacker? If so, how will that affect the rest of the 49ers’ offense?
