Actually, we missed Frederick in a big way. And though he wasn't the same Jason Witten, in the red zone, we missed him in a big way there, too. Once we had another viable #1 WR, it helped, but we never reached the levels reached in 2016... and the difference was personnel.
Playoffs, our offense won vs. SEA. Late, our defense almost made it another heartbreaker. And then had our defense merely stopped the Rams from scoring and, thus also, given our offense 2-3 more possessions... that's a different game. Can't legitimately lay our failure to get over the playoff hump in Linehan's lap.
