Minnesota Vikings beat the Arizona Cardinals 20-9, but first a quick recap around the league:

Andrew Luck retires at 29, and the colts allow him to keep bonus money. Lamar Miller goes down for the season with an ACL injury. Oakland Raiders and Green Bay Packers preseason game reduced to 80-yard field because of safety concerns.

The Vikings somehow unsuccessfully challenged a fumble (stadium angle was perfect). Off game for the offense in general, flow seemed to lack. Olabisi Johnson is looking like the WR3 of the roster, and a lock on the 53. Pass protection continued to struggle, but maybe not all the line's fault. Mike Boone continues to string nice games together, what does it mean for the final 53? Kyle Sloter has another nice outing, is he QB2? Xavier Rhodes looked poor in the snaps he saw, is it overreacting to be concerned? Jayron Kearse and Mackenzie Alexander have several splash plays... again. Mike Hughes still waiting in the wings, does he get PUPed? What the heck is going on with the kicking? Saturday revealed little in the way of clarity on the situation.
