Well, as far as a contingent here, there's me and maybe 13 others I know of.
First, yeah, that's a pretty uneven trade.
That said, I love dynasty because the player valuations have greater variation than in a regular redraft format. What's your timeline? This year? Two years? Four years? Ten? Makes it much more interesting to me. Philosophies differ, current year strategies can change, and even single player evaluations are subject to opinion.
Because of that, I think it is pretty easy, especially in a dynasty format, for another team to propose what might be received as preposterous. It's also a game everyone else is trying to win, too, so I never take offense to outlandish trade offers. I may laugh, but that's about it.
But yeah, it wouldn't take me long to turn that down. I probably would not have countered either. I would guess that you would really have to (1) love Lance Moore and his pron-sounding name and (2) be in a league that really undervalues QBs and draft picks.
