It's called keeping the pipeline fresh/full. Beane has addressed a lot of the team needs in FA, positioning the team to pick BPA. Moore seems to fit that bill at pick 30.
I was thinking in terms of starting this year. I think Morse is too valuable at center, knowledge/experience wise, and provides continuity, especially for Allen.
80% of Allens development is on Allen. 20% is split between Diggs and Daboll.
Daboll has been excellent (mho) in game plans, calling games and in game adjustments.
He has utilized Allen's talents very well and may be why the credit.
Most of Knox's drops were not looking the ball into his hands. A problem since his rookie season.
This is correctable, however one would think he would have corrected it by now.
Give Daboll a lot of money in an extended contract with a clause stipulating that if the Bills win a Super Bowl, he is free to pursue Head Coaching options.
