Moore to convert a third and long. Next, Williams pulled off a (once again under dure s) to DeAndre Swift, which ended in a 42-yard gain.Those two consecutive plays were a sneak peek into Williams's incredible instincts as a quarterback.The highlights of Williams's second drive were a 26-yard completion to tight end Cole Kmet, plus the aforementioned QB scramble, which allowed Williams to show off his speed. Williams wasn't able to connect with talented rookie , but he did target Odunze on two occasions.Overall, Williams provided a little bit of everything on Saturday, and Bears fans have to be thrilled about what they witne sed.More NFL: Trevor Stephan Jersey
