1) Offensive Line 2) Run Game (kinda goes in hand with #1) 3) Offense play calling 4) Secondary improvement 5) Defense play calling, when curveballs come and adjustments are needed.
Not something that can be done immediately, but we've missed in a few areas with recruiting the last 4 years (Got thin at D Line last year, weak at O lineman as a whole the last 4 years, not as solid at secondary as I would like. No true lock down corner....than god for DK).
Should have been Great at WR, but crazy injuries keep 3 starters off the field.
