If efficiency is any gauge of the prospects of a pro football team, the Buffalo Bills are off to a good start. Day One of the Rex Ryan era was scheduled for a morning workout from 10 am to 12 noon. The workout began at exactly 10 o'clock and ended at exactly 12 noon. And in that two hours the Bills split up into various units for drills, then came together for the final 45 minutes to work 11 on 11. And not a minute was wasted.
