You sound so much like the GM in my league I was referring to, its scary (well, more funny than scary).
Don't ask for advice if you aren't happy when people disagree with you.
The point is that you're missing and what everybody is trying to explain to you is that no matter how good an offer you make, no matter how lop-sided it is in their favor, they might still be inclined to decline it.
If you do well with sleepers and under-the-radar players, than more power to you. But those aren't usually the guys that most GMs want. Yes, Jason Pominville outscored Eriksson, E. Stall, Parise, D. Sedin, Iginla, P. Kane, AND Ovechkin last year; that doesn't mean you could ever get any of those players for him. He's got production value, but no name value. And unfortunately when trading, name value is worth more than production value.
Nobody's trying to knock on you though. It's fustrating trading for elite talent because of the unreasonable price tag. But such is the market. Hopefully for your sake, the GM in your league with Ovie is easier to deal with than we are.
