The poll isn't specific enough.
There isn't a one set piece taker in a team, unless he is equally good in both feet, which I've never seen yet. Even the players who are considered to be able to use both feets, that is magnified when it goes to Set Pieces, as it needs a lot more precision than simple pass, or even shot at times. Ricky can use both feets, but I've never seen him make a free-kick using left foot.
So unless, the person is equally good with both feet, or other players are a lot worse than him, and it is better for him to do the other side of the field too(Pirlo), we see more than person doing kicks in a team.
We would have to divide the free-kick takers, as left foot takers, and right foot. Left foot, on the right side, and right foot on the left side.
On top of that, we can also have a set of kick takers, to shoot on goal, and to cross the ball for a header. If Adriano can easily do a kick to shot, he rather won't be taking a cross.
I know, I'm paying too much attention to details
, as FR described me once, but that's just the way I am. Hate me or love me.
