On 3rd and 21, with the other team's pass D being what it is, would YOU take a shot downfield? I think you have to give yourself a chance to make a play. I'm not saying a 25 yard pass, but at least a 10-15 yard slant or something and hope that your WR could break one. I'd have more confidence in my WR making a catch and run for 22 yards than my RB breaking a 22 yard run, especially with how quick our defense is against the run and how inconsistent Tillman is.
