No, milk is not bad for athletes unless an athlete has a milk protein allergy or suffers from lactose intolerance. Milk contains high-quality protein, carbohydrate calcium, magnesium, phosphorous, and vitamin B12, which are involved in bone health, recovery from exercise, metabolism, and various other critical physiological functions [1]. 
Specifically, milk is rich in leucine, an amino acid that appears to stimulate muscle protein synthesis and enhance recovery after a workout [2]. In addition, milk also offers readily-absorbed carbohydrate to help replenish muscle glycogen stores after exercise. Some research suggests that chocolate milk is especially beneficial for recovery because it offers a unique combination of carbohydrate and protein, as well as fluid [3]
That said, milk is not critical for athletes to perform at their best, especially if an athlete has a milk protein allergy or lactose intolerance. For these athletes, consuming milk products can be not just uncomfortable but also, dangerous.
