Any chance you'd care to elaborate on "gimmick team" and "legit success?"
Being a one-trick pony that has no backup plan if the jump shot isn't falling never got anyone anywhere.
I don't buy the logic. Unless you are a truly dominant team that runs the table on everyone, no strategy guarantees success. There will always be chance involved in winning.
If you aren't a dominant team, your best strategy might be a high risk high reward strategy, like Eli Manning style quarterbacking. Perhaps you will never be as consistent as some guys, but you might win it all in a lucky string of games while they are consistently knocked out in the second round.
One problem with people doing these analyses is that there is such a low sample size, that there is no end to the number of ideas that can be claimed to be supported by the data. Did the Utah Jazz not win it all because of strategy? No. It was because they faced the Bulls.
