Not sure how you look at Monk and say "not a pure scorer" when he's a record-breaking scorer on the AAU circuit. Range from past the NBA 3, has a floater, terrific slasher, plays above the rim with ease, has a number of moves to get the ball into the basket at the rim. He has the ability to score in bunches in all 3 levels. I'm not particularly sure how that doesn't translate to being a pure scorer.
Gordon on the other hand really only had two tricks. The 3 point shot, and scoring at the basket. No in-between game, and he was limited as just a scorer.
I figure there are probably two reasons why Eric Gordon didn't become a phenom. 1st one is the injury, and the 2nd one is being a very undersized two guard (who had very, very limited passing abilities).
Monk could absolutely make his money as a point guard. If you haven't seen his passing abilities, it's on par with what you'd expect from an elite point guard prospect. The only deficiencies with Monk are always giving 100% on the court (which Calipari fixes year in and year out with players), and making efficient plays (which Calipari fixes year in and year out as well).
If Calipari coaches Monk the exact same way that he coached Jamal Murray, he could end up with the best all-around player in college basketball by the end of the season. Not just a scorer, he's a terrific all-around basketball player. Pair that with his insane athletic abilities, and you have yourself a player.
