Don't even need the new fetches! The idea is cool, but doubt it would work well in practice on average.
That's not a bad way to do things assuming a normalish sized bench. Have been in some leagues with really deep benches and waiver wires are shit in those leagues though lots of trades tend to happen.
Yeah Graham is a premium player at a position that doesn't really have much after him. In your example you can't just compare Graham with Megatron. You have to compare Graham and whatever receiver you get later and Megatron with whatever TE you get later. Even if Johnson outscores Graham...
It doesn't matter who you pick, one of the others will end up with 1800 yards and 25 TDs while your guy misses 4 games and only has 5 tds on the season. At least that's what always seems to happen to me!
