Friday mailbag: Vikings' backfield outlook? O-line depth? Cousins' future?

Ben Goessling, Andrew Krammer and Michael Rand answer your Vikings questions as they will every Friday before a regular Sunday game. This week's topics include how the backfield will shake out behind Alexander Mattison, the offensive line depth, and where cornerback Andrew Booth Jr. falls in the pecking order. Krammer goes solo for 15 minutes to answer a couple more, plus share a bit of his interview with Mattison about the NFL running back market and how Alexander landed on coming back to Minnesota.
