How do you separate the player from the team with that?
How much of that is due to good positioning and anticipation from the player vs the tactics of the player's team?
You can't really. If you notice similar shot maps across seasons, in different systems or with different teams, it's probably a skill, but outside of that, shot locations and tactics are pretty much inseparable.
I tend to use these individual season shot maps as a measure of forward decision-making. If a player is attempting a lot of long-range shots or shots from wide angles, I'm generally skeptical of their output. Those types of shots are lower quality and, more often than not, a pass or a cross is a better option from those areas. If a player has excellent goal-scoring output for a season but poor shot locations, they might have some difficulty repeating that level of output in the future. I doubt this is the case for Modeste. Most of his shots are central which suggests that he's selective and doesn't waste many possessions with low-quality attempts.
It's hard to say anything meaningful about Modeste's ability to
generate good shots without understanding Koln's tactics or without having his shot maps from Hoffenheim. But the fact that he tends towards these good shots is a solid indicator that he makes smart decisions in the final third (which would help explain the consistency of his output in the Bundesliga).
Edit (just for fun): I couldn't find it in the same template but here's what Lukaku's map looks like from last season.

But all of those centrally located shots pretty much confirm what the eye test tells us -- Lukaku makes good decisions in the final third (even if he's a little overconfident with those shots from outside the area).
