If we are really honest with ourselves, isn't it true of every offensive squad on the Dallas Cowboys.
What known commodities do we have at the RB position? I think we have a short yardage specialist in Zeke. Everything else is speculation until we see something special happen.
The same is true at TE. We have Jake Ferguson but for all we know Schoonmaker might have a real breakout after al his setbacks the previous season.
The O-line will, most likely, begin the season with two rookies, one of them protecting Dak's blind side as the LT. Has Steele now fully recovered from his injury he sustained before last season? We know it takes longer than a year to get NFL ready.
I would say there are a ton of questions in regards to whether Lance can step in and actually compete as a starting QB. There is obviously questions about Dak's ability to take the nest step by defeating good teams in the olayoffs.
