Probably not.

2013 was our golden chance with Rob, I just don't think we were tough enough in the playoffs on offense.

Our D did everything in that Seattle game to get us a win whilst our offense couldn't manage a first down.

O line was outmatched that day.
Armstead was a rookie in his what, 3rd game?
Grubbs and Goodwin were man-handled all day.

Graham was 1 for 6 for 8yds.
Offense was 25% on 3rd downs (normally 43%)
We ran 6 screen plays, gaining positive yards on 1....

Yeah, that was a bad day for our offense even without mentioning Lynch ran for 140yds

Exactly, plus most of Lynch's yardage came near the end when our offense had 3 consecutive 3 and outs.

Can't ask the D to hold up when your O is putting them straight back out there every 30 seconds.
