Here's what I noticed this year in regards to the passing game
1. A vastly improved receiving group. You have Martin, Toure, Manning, Betts. Each of these can stretch the field.
2. A much better deep ball and a much better ball in that 10-20 yard range from Martinez
3. Not totally there yet, but better pass pro from oline. That 1-2 seconds makes a big difference.
Regardless of who is calling the plays, If 1, 2, and/or 3 are not true, then you have no downfield threat.
Lubick is calling plays.
