Teams will still sell out against the run and shut it down.
Not to mention the difficulties that come with being a run first team with a bad defense. If we done score we will find ourselves down quickly and the run game becomes useless.
You can still be a run heavy/balanced team with playmaking WRs and TEs. It doesn't have to be strictly a rushing team to be a physical team. Obviously, if you go with a rushing/balanced team, you have to have a good/great defense. The rebuilding/retooling of this team can happen in this draft.
