This is an old argument here. I think we've seen some constructive ideas in the Suggestions Forum in the past, such as incorporating JS or JR training with FT training, etc. A couple of years or so ago I know that I've wanted to have height be a factor in FT training (there is science behind the idea relating to the angle of the shot and the resulting minor axis of the ellipse the ball must pass through, and I'm sure data backing up performance of FT% vs. height has been looked up in real numbers in basketball data analysis). The basic idea behind the history of complaints is that it just doesn't make sense that a player can be a great outside shooter from the field but then not hit FT very well. Sure, the players with this highest FG% also tend to have lower FT%, but that's just because the players who shoot well from the field tend to the be the players only shooting inside shots (see Tim Duncan, Shaq, etc.). I'll agree that FT shooting is part mental and it's not really a perfect equivalent to shooting from the field, but come on! In BB, it's possible to have a player with 16+ JS and JR, yet atrocious FT%. I think the complaints are about wanting a reality check in this matter.
Otherwise we all love the game. Except that we hate that we spend too much time of our real lives here. sigh.
