It might have something to do with a defense that regularly gives up 40-50 points a game.
Which is part of my point I intentionally left out. Teams need to have good balance throughout the 53 men. We have good WRs that fit our system well. Our WR production is way up over last year and will go up next year. Tanne doesn't need a big physical WR, he needs a line. A line makes the RBs life easier too...less blocking, actual holes to run in.
