I liked this article a lot - it discussed a lot of great points that are almost essential for getting trades done in many leagues. I also wanted to mention one more specific strategy that wasn't discussed in the article but was showcased in the trade he used as an example. This is something that I've only recently picked up on, but it's already helped me pull off one trade that wouldn't have happened otherwise.
It can sometimes be helpful to make the deal a lot
bigger and more complex than it has to be in order to get a
smaller deal done. The author of the article exemplified this perfectly when he traded Reyes, Izzy and Clippard for Crawford, Mo, and Dontrelle. Reyes and Crawford are basically the same kind of player (position aside), so it's unlikely that the author had any particular need that Crawford helped him in that Reyes wouldn't have. However, the other owner clearly valued Reyes a lot higher than Crawford, and that allowed the author to upgrade his pitching nicely.
So the general idea here is to include a swap of big-name players into a smaller deal. As another example of this, I traded Crawford and Kevin Gregg for Soriano and Harang a few days ago. The guy wasn't willing to do Harang for Gregg, but after talking to him, I found out that he was looking to move Soriano if he could get another first rounder in return. If Soriano doesn't pick things up, then I may come to regret this trade. But assuming that Crawford and Soriano end up being about equally valuable, then I filled my need for a starting pitcher without giving up more value than I wanted to.
Also, if you're in a league where the commissioner is a little trigger-happy with the veto, using this strategy can help prevent your trades from being vetoed because any perceived imbalance in the side-players in the deal (i.e., the real reason you're doing it in the first place) is outweighed by the big-name players being swapped. To go back to the author's original example, Izzy+Clippard for Rivera+Willis might have been vetoed by some trigger-happy commissioners, but with Reyes and Crawford thrown in there it's very unlikely to get vetoed (unless the commissioner is a real d-bag).
Just wanted to throw in my two cents based on recent experience.
