Pretty difficult to do unless you are very special. The demands of playing one sport are pretty demanding let alone two. Toby Geirhart is the most recent player I can think of.
Our friend’s son went to a DIII in California that plays baseball at a pretty high level, and he played football and baseball for one season. After the first season the Baseball coach told him that he could continue to play both sports, however he would not move him up the depth chart as he could not risk loosing him to a football injury if he was going to be one of his frontline guys. (he is a pitcher)
He dropped football and is now in his Jr year and doing quite well baseball wise.
