Completely different kinds of player. In fact, McD isn't like Korver at all. He can score in many more ways. He can take it off the dribble, post-up, cut off screens, stop & pop, & has underrated athleticism. All he needs is time. This kid has Wally Szczerbiak 2.0 written all over him. He can be better than Dunleavy. He can be better than Korver.
Will he be a better 3 point shooter than Korver? Maybe, maybe not but make no mistake, if he fulfills his potential, he could make an All-Star team without being a replacement like Korver is.
