Clyde Drexler is the guy Brown most reminds me of.
Both are roughly the same size - 6'7", 215 pounds or so with similar body frames. Both were smooth to the basket and explosive around it. Neither was a good shooter early in college (Drexler shot 58% on his free throws his first year, Brown was 65%). Of course there are some differences. Drexler was a considerably better rebounder and played closer to the basket (hence a better shooting percentage from the field) while Brown is more effective at drawing fouls but otherwise both players just seem to be the same kind of North-South, leap-at-the-basket offensive players. Both guys could cut from side to side but at their best they play a North-South basketball, taking it right down the middle. Of course Drexler is the better dunker and a better leaper but Brown is no slouch in either category. If Brown played for 3 years with The Dream to play interior defense I think his highlight reel would look quite similar. Both have quick hands and both were a bit raw coming out of college. For instance, Drexler scored only 7 ppg his rookie year in the pros and shot about 45% from 2 point land and I would not be surprised if Brown posted similar statistics this year.
Of course, Drexler turned into a 10 time All Star. I'm predicting Brown will make at least one All Star game as well but only time will tell if he approaches Drexler's career. Drexler worked on his shooting and added some moves to compliment his explosive nature. It was his hard work that lifted his pro game into being a Hall of Famer. It's up to Brown to do the same.
