Rayvonte's stats are readily available and they do not argue for him being a great outside shooter...and maybe not even that good of a shooter overall..he scores his points because of the VOLUME of shots he takes!
Rayvonte Rice was 67-183 (36.6%) from 3-pt in the regular season as a senior, .....then he went 2-14 (28.6%) from 3-pt in the two games at March Madness, Champiagn Centennial losing both games (49-42 to CC Hills & 73-59 to Marshall) to end up taking the 4th place trophy and 31-3.
As a junior, Rayvonte shot 31-92 (33.7%) from 3-pt in the regular season...
Then in the two games at Carver Arena during March Madness his numbers were less impressive..3-10 (30%) from 3-pt..although he does get to the hoop and score on a lot inside against high school opponents, so his overall shooting pct is above 50% (but he sure won't get as many of those inside shots in college)
..so it the stats over a pretty broad period can be used...his entire junior and senior seasons in high school, then he is a 34% shooter from 3-pt range which is not particularly good for a high schooler given that they shoot from closer in than NCAA and seriously, Rayvonte should be able to get good shots because of his size and the relative smaller size of most of the guys who defended him for those two years..... not exactly a scorching shooting percentage for a guy playing against kids who'll never play in college and being bigger than most of them.
