Mailbag: Could Thompson wear green dot?

I remember reading in the 1970s that Tex Schramm said the best way to draft in the late rounds was to draft a football body and hope to find a football player in it. This seems better to me than drafting undersized defensive backs and linebackers who were good at the college level but won't hold up at the pro level. What do you think?

Which position do you think is more important on the offensive line, left guard or left tackle? I realize left tackle protects Dak Prescott's blind side, but I feel guard is more important for the running game, which will then help the passing game. Given that, Tyler Smith is great at either position, but I think he is more needed at guard. What is your opinion?

Do you think Dallas is all set at the running back position? Javonte Williams had a solid year, but Jaydon Blue didn't seem ready, and Phil Mafah spent most of the season on IR. Is Malik Davis the answer at No. 2? Do you see them adding a back in the draft?

One of the biggest needs going into this offseason has been linebacker, and there are still plenty of good veterans out there – Bobby Wagner, Devin Bush, Germaine Pratt, Deon Jones, Devin White. I mean, surely one of these guys is better than none of them. What am I missing?

I recently read your Next Man Up series, and it stated there is always a possibility of moving Tyler Smith to left tackle again. Shouldn't the Cowboys evaluate Tyler Guyton for the long term, and if he is not the answer, draft or trade for a left tackle? Given Dak Prescott's window, this year is too important to be uncertain on the O-line?

With what we have seen in free agency so far, I feel that (once again) the Cowboys have no real intention of signing players who would help them truly compete for a Super Bowl. Do the Cowboys still need to make a big splash to convince us this team is really heading in the right direction? 

The Cowboys have always stuck to best player available in the draft. Is this the year that's finally off the table? If an offensive player at a skill position is considerably higher on their board, and a trade isn't available to them, do they pass?

How far up could the Cowboys move in the first round if they packaged the 12th overall pick and their third-round pick in a trade? Who would have to be available for you to trade both picks to move up? 

I don't understand all the 1-year contracts. It seems to me they set the stage for the Cowboys being in the same place again this time next year. I get it in the case of older or injured players looking for a prove it contract, but why not sign someone like Cobie Durant, who is coming off his rookie contract, to a multi-year deal if you're convinced he can help your team?

Since the non-exclusive tag allows players to negotiate with other teams, why haven't we heard anything about George Pickens' agent trying to work on a big contract with another team? I would think no offers would mean less leverage when it comes to negotiations with the Cowboys. Your thoughts?

I remember in years past the Cowboys employed older, veteran backup quarterbacks like Brad Johnson, Jon Kitna and Andy Dalton. Was that a front office preference or coach's decision? If it was the front office, what changed? Would you prefer they had more experience at backup QB?
