No. There is no need for statistics when you have the individual at your disposal and work with them day to day. Treat them as a human. There is no need to make vague statistical guesses, the data you gain by actually interacting with them is far superior, no? It would be like cutting John Stockton from your basketball team because he is short and white, there is no need to make statistical judgements like that when you can watch the actual player on the actual basketball court and assess them properly.
