just for the record, playing all sims on the road is a valuable tactic for a certain slice of coaches. that slice is generally coaches in a really hard conference, who are going to get their ***** handed to them, who need the weighted wins (away wins) in non conf to soften the blow of conference play.
for most other folks, an all sim schedule is absolutely not optimal. for any top 25 or so team, by talent/coaching/etc, it is not the best way to go. for most others, its also not the way to go... but it is always important, to note if a gimmick strategy is viable at the high end or not. its viable, because its not that horrible, but its far from optimal.
all sim schedules were popular before the projection report came out, largely because of laziness - it was possible to spend 20m on the last day and still come out in fairly good shape. but with the projection report heavily weighting record vs top 25/50/75/100 teams, sims just don't cut it anymore, for the truly competitive.
