Pippen was the fifth pick in the draft and was basically the prototype for the modern wing player. I wouldn't say he entered the league as "dogshit".
I also disagree with the under-rated sentiment. He's a many-times all-star, many-times all-whatever teamer, two-time Olympic gold medalist, key member of six NBA champions, and a hall of famer. He's widely recognized as one of the best players ever at his position (name five small forwards better than Scottie Pippen. Larry Bird. Dr. J. Who else? Dominique Wilkins? Pippen was a much better all-around player.) and one of the best defensive players ever at any position. Who exactly is underrating him?
