This is a great article, and it is hard to argue against. But, I will... sort of (in money auction leagues). I prefer the $1 homerun hitter. Patrick, in the article, says that it is hard to pay for steals... and this is exactly the reason why I want the $1 HR guy.
Face it. Chicks (and fantasy players) love the long ball. BIG money is spent on the homerun hitters which is why you find these 15-20+ SB guys available near the end of drafts (e.g., I got Lugo for $3... look, nobody expected him to hit sub-Mendoza, and I still think he will hit .230 or so when all is said and done; I got Ryan Theriot in our free, end of the draft farm team serpentine).
So, if you can save money to get power, you can allocate that extra money to pay big on one of the big steal guys... Reyes, Rollins, Crawford, etc.
At the most basic level, presumably a guy with power is going to help you in HR and RBI versus the SB guy, well, primarily giving you SBs. Two categories vs. one, primarily, is the more valuable. Of course, one could argue that SB guys score more runs...
And, my money league, though, includes OBP as a cat (instead of R scored), so as to add to the confusion.
In the end, based on my observations, a lot of money is put out in the first ten or so auction rounds on power. If you can get this cheap, this is essential. It is not hard to load up on 10-20 SB cheap guys near the end of the draft, notwithstanding SB scarcity (vs HRs). And, to win a league, you don't have to win the SB category... somewhere in the middle is fine, I think.
