This is one of the more interesting trades posted here - however 12 team ppr, just isn't enough information about the two parties involved in this swap to make what I might consider an intelligent comment on it. I think that with more info on the rosters and owners involved - including their prior accomplishments in the league (and elsewhere if available/appropriate), would get more of an interesting response from more forum participants.
Dan H, you of all persons should know that by now. Thanks for all of your contributions in this thread, I've learned a few things from you in a brief time.
I'll try to add some more detail if it helps. This league's going into it's 7th year and is probably my favorite of the many I'm in because the owners are all active and knowledgeable. Posted some other trades from this league where I've flipped from extremely WR-heavy to RB-heavy in the course of the past few months. It's a normal PPR league with 1/2/3/1 and 1 flex. (TE get 1.5 PPR). It is shallow devy with 12 college players draft-eligible the next season available in each rookie draft.
This trade was my attempt to add a little more upside back into my shallow WR corps by moving Abdullah for Bryant. I view Abdullah as a relatively low-ceiling RB2 because he probably will never be a 300-touch guy or big goal line scorer and Riddick caps his receiving upside. Bryant is obviously very boom/bust. Could be out of the league next week or could become a superstar and still only 25-years old.
I had offered Abdullah straight up for Bryant and it sat out there for a few days, so I knew it was close. He never rejected but offered me Bryant for Abdullah and the 2.09 while the pick was on the clock. I countered by asking for his 3.08 to be part of the deal and he quickly accepted. The 2.09 ended up being Cooper Kupp. I'll end up with Gerald Everett or Adam Shaheen with the 3.08 (I'm on deck).
