Wow, I am really surprised at how many think trading is not important. The 2 for 1 trades late in the season to get the best staring lineup possible, or key timed trades to avoid important bye weeks are key. Trades to recover from injuries are also a mjor factor. I agree many trades are sideways, trading Marshall for Green doesnt mean much but tradng your WR3/4 that is performing like a WR2/3 and a RB2/3 for a WR1 or RB1 wins championships. Trading a stud for another with an easy playoff schedule a sound strategy, trading a studs on teams that may sit players week 16 is strayegy. Doesnt always work but increases your probability of wining
Those sort of illustrate my point about trading in FFB not making a ton of sense in many cases.
A win/win trade in FFB is pretty rare. 2 for 1's and buy low/sell high are by their very nature going to have a fairly clear winner and loser. Getting the "2-side" of a trade is almost always a bad idea, and of course, buying a player for more than he's worse (and vice versa).
Not there's anything wrong with having a loser in most trades, but it also means that in most cases, one of the parties should not be trading.
Not that that's the case in every trade, but in FFB, it's a whole bunch of them.
Sometimes 2 owners are just going to value the players involved different, but that really should be pretty rare. After all, it wasn't so long ago (the auction) that the current owner valued his player more highly. You'd need 2 owners flip-flopping in their valuations of each others players. Happens, but it really shouldn't happen that often.
