Simple solution, preset your player values. I preset several of my players. That said, you should show up to the draft because it is the single most important event in the season.
I'm not really worked up over this and all your typing hasn't convinced me that we need to make adjustments. If you don't show up and don't preset your player values, that's tough luck.
I do disagree with your assertion that a team can't be competitive for a playoff spot if you miss the draft. Having a solid core of 7 guys that are supplement by several guys in the low to mid 100s can make a team competitive with a little waiver wire activity. And once you make the playoffs, anything can happen.
Still I think the simple lesson here is preset player values and show up to the draft. I think so many people missed this year because you proposed it to be Tuesday and then at the last minute change the day. Give us several weeks notice with time to prepare and most/all managers will attend.
