Oh, 100% agree and I absolutely don't expect any in-season moves. And the guard positions I'm not overly concerned about because, as you said, injuries and such are the biggest issue there right now and there's at least light at the end of that tunnel.
But they need two new quality tackles. Anderson and Reiff were at best backups to begin with, and obviously it remains to be seen if the move with Sow is going to pan out albeit, it would be great if it did. And if they go to the well again with Brown, that would be extremely unwise.
Any moves for a receiver also wouldn't come until the offseason because I expect them to be sellers ahead of the trade deadline, especially since the odds are pretty good they'll be 1-7 or - should a miracle occur - 2-6. They don't have enough to warrant any additions midseason.
