the rage of the forums in that era was that -5 was an exploit, I think it was -5 man, but all -5 was considered I think the word 'gimmick' might have been used. Tarke ran a bunch of simulations to prove it wasn't, he posted them, same two teams vs each other, 500 games each running all 11 defenses, -5 thru +5. 0 was the best, -5 the worst, +5 the second worst, BUT all were pretty close, and some were out of order (+1, -1, 0 were very close to each other)
additionally, if teams doubled (DT'ing was an upgrade to the orig engine) the best perimeter players & played -5, it worked even better according to the forums.
at the time, all my west conn d3 title teams and all ten of my teams, ran FCP with 0, I almost never changed, and if I did, it was +1 or -1. anyhow, as result of all this posting, I decided I'd try the opposite of the defense everyone thought was so great. In addition, I think at the time, nobody had won a title using combo defenses, so I set out to show I could win titles without FCP'ing, so I switched all ten of my teams to +5, dt'ing the best two inside guys, running man - fcp combo. I ran it for about 2 seasons of ten teams, so 20 or so, not sure if there even where ten worlds back then, but I think there were.
I kept winning, didn't really think I had unconvered a glitch or anything, cause I also was winning without it.
but oldave didn't think my defense was fair. He later sitemailed me explaining that he'd worked with CS to change the engine when a team dt'd big men. It turned out CS/tarek found out that in the code, when one dt'd big men, it counted those big men as potential defensive reobunders, so instead of 2 or 3 guys I had 4 or 5. All ten of my teams led the nation in rebounding (I really didn't even know that, but oldave told me, tarek never contacted me), and the margin wasn't that close (say by 5 in most worlds, even though back in that day, I almost always started 3 guards). so I got the benefit of +5 (I think I ended up +2, back then I used to experiment all season long with most of my teams) to stop 3's, I got the turnover benefit of some pressing, and I almost never gave up an offensive reboound, plus I dt'd both of the other team's star big men.
You can judge me or my intentions, feel free to. but I must admit, I never gave my strategy a 2nd thought at the time as either being a glitch or unfair, until oldave sitemailed me and told me what took place and why. I don't think anyone but oldave and I (and tarek) knew anything about this, but oldave is the guy who could really tell the story.
