durantjerry,
geekor,
I think I already said it before, and your posts lead me to repeat the info:
Middle defense is not undervalued anymore in the TSN system. In the past, we basically didn't pay for having defensive double-plays, and for great centerfielder arms. So teams with ss-1 and 2b-1 and cf-1(-4) were certainly advantaged. This advantage lasted for a few years, but in recent time, TSN acknowledged the problem and put a price to those advantages.
So, to summarize, the belief that it's easier to win with great middle defense wasn't a myth before, although it is now a myth (or I should say, a false belief). As we speak, I have a team at 97-55 win a 3e25 ss and a cf-3e8 (+2). So I have no doubt that a team with poor middle defense can now win with the same ease as teams with great defense.
You might object that Daniel teams were based on the past seasons, and had success nevertheless. I would claim the following:
1) When I checked Daniel data, he had tried three or four teams with extremely poor defense. One had great success (probably the one geekor refers to), one or two had records a bit over.500, and one had a very poor record. Thus, the overall sum of the teams I checked was very much closer to .500 than to .600.
2) But, you might say, .500 isn't too bad. If poor defense were bad in the past, we should expect .400, not .500. The reason he still got .500 instead of .400 is that there was another bias in TSN, which has also been corrected (in fact, over-corrected, in my opinion). We came to realize, with Daniel teams and other data, that outstanding offensive players were not priced appropriately because they were generating more offense then predicted. It will too long to get into details, but in short, if you assemble a line-up with great offensive players, you build up your offensive chances in a way that will outweigh the predicting models we had. So, to come back to Daniel teams, when he was concentrating his money on offenses, he was compensating the negative bias towards bad defense by this offensive build-up positive bias and generating .550/.600 seasons. But when he was spending his extra dollars on pitching, he wasn't compensating for the negative bias associated with bad defense, and he was getting .400 teams. To give concrete examples, Bonds used to be priced around 14M in his great years. For the same price, you have nowadays Pujols and D.Lee who are not even close of Bonds's potential. I tried a team where I spend almost 70M on offensive players, and played in Kaufmann to make sure I wouldn't get an upgrade with playing in Coors, and it won't even finished with 70 wins (in fact, I believe you were both part of this league).
This doesn't mean you can't win by putting all your eggs in offense. You can if you select the right stadium and the right relievers (which I haven't in my 65-win team). But it is definitively harder to win with just offense than before.
