Most stats that have a real impact on the outcome of a game mean something, they're not just dumb, blind, luck. Whether it's shooting, rebounding, turnovers, steals, blocks, etc., these stats not only significantly determine the outcome of a game, but they're also indicative of a team's ability. But there is one big exception: free throw defense. For obvious reasons, this stat has little to do with any abilities the team has, and has more to do with the other teams' skills. And if we look at a scenario where everyone has roughly the same opponents (such as in conference play), large differences in FT defense are fairly attributed to luck.
In other words, we have to count that against them in the coming season. A solid efficiency number that was achieved, in part, through excellent FT defense must be discounted. So if your team had great FT defense last year...that's not good news.

Opp. FT %
Some good news for Buckeye fans (as well as some aggravation over the fact that some unlucky bounces prevented them from reaching the NCAA Tournament last season).
And just to prove this isn't some sort of home-court phenomena, here are the leaders from the 2006-07 season:
Opp. FT %
If this had something to do with home court advantage, then the Orange Krush really need to step up their game. They were at the bottom of the Big Ten in 2005-06 as well (75.2%). They need to get back to their 2004-05 form (68.7%), but that goes for the whole team, really.
