Why doesn't anyone project any running back to be drafted within the first round in the 2019 NFL Draft?

Because NFL team have adopted a more passing theme than the running theme. Most teams have Veteran running-backs such as CJ Anderson, Jonathan Stewart, and Adrian Peterson. And its because of the age gape for QB’s which leads to worse game performances which = losses. And anymore big time college QB’s such as Baker May-field, and Lamar Jackson. Both were chosen in the first round. Baker was picked first overall by the browns, the browns have been a team with a struggling offense, and had not won but two games within the past two seasons. The main-center of any teams offense is the Quarterback! Baker is a dual threat QB, which means he can be a impact in both rushing and passing. Also linemen are needed in order to block for a run/pass. You can have both a flashy quarterback and running back on your team but it doesn’t mean you’ll gain yards. Having protection is everything! Also if you keep having a shootout ( no defense game ) and go against a team with a great defense, you do not really stand a chance. “Defense wins championships” running backs are not simply important as a QB, WR, OL, and defense anymore.
