Rose gets in, gets clobbered, no call. Dwayne Wade drives, gets touched, and a foul is called. This seems to happen often, but is it just perception, or reality? Let's do a quick, albeit rough, analysis of a few stats. Basically, I calculated what percentage of a player's points comes from free throws. Based on the top 50 scoring players (PPG), this is what came out:

It is a lot to go through, but I divided the FTA and FTM by the PPG to come up with a percentage, averaged them up, and saw which players were over or under the total average. (Green is over, red is under). I also show the difference between the actual and the average for both categories, and also added both categories up to see if anything else popped out. In its most basic form, we can see which players score more based on their free throws.

It is tough to draw definite conclusions. We can see that Howard is fouled a lot, but he misses almost half of his FTs. Also, only Ellis and Rose are below average of the top 18, and Dirk is thrown in there under the FTA category. Does this back up the prior perception? Perhaps. 

Kevin Martin looks really out of place. What does he do differently?

These stats could also be an indicator of how a player plays. Ray Allen is well below the averages, but he is a shooter and someone you do not want to foul.

Tell me what you think. I hope this made some sense.

Note: I hope no one has done this before. If they have, sorry, but this came to me a few days ago.
