No matter how badly I might feel about the Viking's OL during a season, I can take solace that at least things aren't as bad as they were for the Falcons that one season when they had to have two TEs play OL (I can't remember if they went in at tackle or guard) because they'd lost so many people to injuries that that is literally all they had available who knew the blocking scheme.
I misremembered. They lost three OL players to injuries and put a TE in at RT in the 4th quarter since that's all they had left.
