Key match up

Vikings RT Marcus Johnson vs. Lions LDE Cory Redding and Kalimba Edwards.
This is getting old. But the weak link to the offense right now is the Vikings' second-year right tackle. I thought his performance Sunday in Buffalo might have been worst yet, and that's saying something.
Redding, the starter, isn't much of a pass rusher (four career sacks). But he stout against the run, and Edwards comes in to bring the heat off the edge. Edwards is 6 foot 6, and he's explosive. Last season, he had seven sacks.
Johnson has to start turning the corner soon, or the Vikings may be forced to turn to veteran Mike Rosenthal coming out of the bye.
