Insert Knecht's typical ranting about how the game was, is, and always will be horrible forever and ever
To provide a counterpoint from Knecht's vitriol about realism:
From a game design standpoint, a FT skill makes perfect sense. It allows inside and outside oriented players to both increase their abilities on the line without penalizing either type of player. Without the skill a pure center would by necessity need to get their JS and JR up in order to shoot FTs more effectively which is obviously less effective than continued training in traditional big man skills.
As well, it offers an extra option during low game training weeks other than GS and Stamina training. If FTs were taken away, Stamina would be the premier training option for increasing your team's output. However, Stamina can go too high as well which causes difficult to manage minutes in regards to GS, so it needs to be balanced in a training regimen. At the moment a team that's good to go on Stamina and GS for a low game week can still improve their team. There would have to be something else implemented if FTs were taken out in order to not frustrate a well managed team's owner during these weeks.
Personally, I'm happy with the skill. It does what it says, it's an elegant solution to the difference in IS/JS/JR in regards to FTs, and it provides a valuable increase to team performance during off training weeks. Can't ask for much more than that.
