Last year the short and intermediate passing game were non-existent. Being able to throw an effective bubble and slant will be a huge change.And a good running game to keep the defense honest and open up the passing lanes more.
Having a big, strong WR like Banks will help open that up, along with a QB that has some semblance of accuracy.
A slant, bubble, crossing route available will change the offense and help the o-line out a ton.
