I hated JJ Redick in college. He was one of the most irritating players to me because he seemed so one-dimensional. At Duke, he definitely was. In the NBA, he's developed into one of the more interesting role players in the game. He bulked up considerably, works harder than almost anyone, and he learned how to drive/dish and go to the hoop without fear.
Jimmer Fredette, out of BYU, will likely be very similar for the Kings. The fact is, 85% of guys in the NBA are role players, not stars. Redick plays for the Orlando Magic and is thus in the shadow of Dwight Howard (don't hold your breath on that one though, he could be gone very soon). That being said, Jimmer was the leading scorer in the NCAA last year. If Brandon Davies, one of BYU's best players, hadn't been suspended right before March Madness began, "Jimmer and the Fredettes" may have beat Florida in the Sweet 16 and moved on considerably.
It's easy to say that not just anyone in college has the experience to dominate in the NBA. This is probably the case with Jimmer, but that's okay. He has a few tools that will work on more than half the guys that defend him: a gnarly crossover (1:05 in the video), the ability to elevate and bomb threes despite his short 6'1" stature (1:43), and an explosive first step that allows him to drive (4:20) and avoid the fact that he's not fast but rather quick.
Some thoughts from Alex Kovaleff, high school prep scout:
"I’m interested in seeing him play off the ball. He likely won't be able to create shots in the NBA so his success will be finding smart ways to get open because he’s not very fast. For him to have success, he will have to be an under-sized shooting guard. He will be best on a fast-paced team that doesn't rely on defense."
The Kings aren't quite the Phoenix Suns in their Mike D'Antoni days but they could definitely be getting there. Jimmer could work in Westphal's system and will likely be a solid addition to the Kings' guard-heavy lineup.
