I disagree with the article. Nagy added speed when he got here (not that its been helping him). The 2018 roster featured Taylor Gabriel, Tarik Cohen and Trey Burton, certainly not a slow team. And they have continued to add speed along the way.
Speed hasn't been the Bears problem in Nagy's tenure. Its been poor QB play, poor game-planning, bad play calling and a bad running game.
This idea of the Bears being a slow power running team is stale and not based in fact. The Bears have turned over the offense for Nagy. Only one offensive starter remains from the Fox era.. Cody Whitehair.
