Personally I believe PBTR and Jerr have excellent points. Although I agree that it would be nice to see more trading it is also difficult given the nature of the game: Highly specialized teams both to park and divisional matchups limit greatly the player pool that fits those strategies.
This set is a bit washy with extreme parks but even then I see teams that are highly specialized out there.
As Jerr mentioned above, sometimes the offers are not good.
One of the other reason why I think trading is becoming difficult is because there seems to be a certain fascination from certain managers to just get "names that work" I see some managers that assemble teams/winning combos by just trying different cards but I really doubt that they even stop to think why their good teams win and why the bad teams loose, that is that in some cases even managers with winning records don't really understand how they can tweak a winning combo they just memorize things like: such-and-such is good value in Shea, the-other-one is good for Coors, etc... The problem with this is closely related to PBTR's point. It has nothing to do with understanding the intricacies of the game or not, it's rooted in what sometimes happens with rating systems and the "Whose the best CF in 07" threads where what they end up creating is a rush for some recurring cards.
So, at the risk of sounding like a snob, IMHO what would really help promote trading is if some managers would actually [b:c39db105a7]think[/b:c39db105a7] [i:c39db105a7]why[/i:c39db105a7] is it that their teams are losing -or hopefully winning- [i:c39db105a7]what[/i:c39db105a7] is it that they need in order to change their "luck", [i:c39db105a7]How[/i:c39db105a7] is the proposed trade helping -or not- so that we actually have[b:c39db105a7] managers [/b:c39db105a7]with [b:c39db105a7]strategies [/b:c39db105a7]as opposed to a color-by-number kind of approach.
