That’s a nice question, in which the answer isn’t that simple than I rather have this one than that one.
It all depends on quite a few factors
1. The skills or the expected skillset expected direct opponent (the player he is playing against)
2. The skillset of the player in question
3. The inside attack played, Look Inside or Low Post
4. The skillset of the other players in the team
5. The defence you expect your opponent to play
6. The average skill of the team which you’re playing against
7. The strength and weaknesses of the own team.
Unfortunately there isn’t just one answer to your question. The player with JS = 9 + IS = 14 will be referred to as player 1, The JS = 3 + IS = 16 will referred to as player 2
I can write out all of these scenario’s, but I’m probably able to write about 10 pages about this question. So I’ll try to summarize it, for the most common situations.
Player one is more often suitable against opponents whom you have to profit from your sideskills, and when you know you’re headskills aren’t good enough. That almost always means playing a Low Post, since you make use of this more with this tactic, and when they got rebounding, you like to wait your players only to take the best shots. Player two is probably better if you’re team is good in ball circulation (handling, passing), and you are probably about equal in headskills with your opponent, or a bit better. Player one would again be better if the opponent is a lot worse so you can use both strengths.
