We need upgrades. It would improve this team.
But based on choosing between Taco and Heath. We need an upgrade at Taco's area, the defensive line. There are so many unknowns waling into this season.
How will they resolve the Gregory situation? Which Taco will show up for camp and the season? Will they have stoutness this year in the interior of the line? How many teams are looking at the Rams formula late in the season to beat up on a Marinelli style d-line?
Yes, we can write just as many doubting questions if not more about the Safeties and Heath, but I beleive you win the games at the front lines.
Plays are made in this league in the first three seconds. The league is designed to make the passing game successful.
Of the top (15) passers in 2018, and yes Prescott was in this group, the lowest completion percentage was 62%.

Disrupting the passer, and stopping the run is winning football. The players and unit who can do this the best is the d-line. They are the front lines of making the QB's life miserable.
They set the table for run defence in not only disrupting the blocking schemes, but they also keep things clean for LBs who fill in gaps and support with tackles.
If you have a safety who has a crap load of tackles you have one of two things. A guy who is crashing down a lot and susceptible to play action or you have a porous defence up front, and the safeties have to be the last line of defence.
It is not a sound game plan to rely on the last line of defence! You can have schemes to ensure they cover the areas of greatest risk, and support against offensive threats, but having them isolated one on one is risky. That's why we dumped Ryan. The coaching staff at the time thought Ryan's defences were fundamentally unsound.
Here is a great quote from Billick. It's an easy concept, and the principle has never changed in this ever evolving pass happy league called the NFL.
“If you can get pressure, the really good defenses – and when we went to the Super Bowl, one of the hallmarks of our team – was our ability to put pressure on quarterbacks with just a four- or five-man rush,” said Billick, who is now an analyst for NFL Network. “When you can do that, then that gives you a lot of latitude on the back end to play matchup, man, matchup zones, trap zones, it just gives you a lot of latitude. If you have to bring six and seven guys on a regular basis, that’s great but you better be pretty good on the back end."
I don't know the budget the Jones and the coaching staff is working with. I'm going to naturally assume that Richards had got to be in on the conversations going on about personnel he would like for his style of defence along with Marinelli.
If there is one glaring question that hasn't been raised by Cowboys' fans everywhere it is: "Where was Richards opinion about the value of Earl Thomas if he is to be the saviour of this defence?" Why wasn't he thumping the table in front of the Jones and ensuring they would drop all resources to get the man?
We need upgrades. The Earl Thomas ship has sailed. I would like to see this team focus on shooting its wad on the defensive line, and supporting immediate upgrades in this area through either the draft or remaining talent left in free agency.
