Well there are such things as advanced stats...
PER
RV = 17.3
BDJ = 29.2
(for context, Hogue, Naz, and Edozie are all between 17 and 19... Niang is a 25, Monte a 22)
The Player Efficiency Rating (PER) is a per-minute rating developed by ESPN.com columnist John Hollinger. In John's words, "The PER sums up all a player's positive accomplishments, subtracts the negative accomplishments, and returns a per-minute rating of a player's performance."
RV would be a near starter on this roster given that performance. Might even make sense to go Morris/Long/Hogue/Niang/McKay and have him as sixth man. BDJ is a studddddddddddddddddd and probably our best player (so far). Definitely won that trade according to this metric.
WS/40
RV = 0.105
BDJ = 0.271
So BDJ is roughly 2.5x times more efficient towards helping the team win in his minutes and position. BDJ has just been a wildly efficient, statistically productive player in the same vein as DeAndre Kane. I know, sacrilegious, but he really is playing that well so far. They're both big guards that score a lot and suck down all sorts of rebounds. The only real difference this year is Monte Morris is more of a "finished product" for BDJ and does a lot more ballhandling than he did for Kane from last year given it was a freshie just starting out.
For context on the WS/40 on our squad...
0.271 BDJ
0.240 Niang
0.233 McKay (given a small sample size, though, but he put up nice numbers against Drake)
0.218 Morris
0.212 Edozie (much better offense this year and he's efficient about drawing fouls and nailing FTs)
0.160 Naz Long
0.159 Hogue
We're good without BDJ (and the Iowa game proves it), but he's reallllllllllllllllllllllllllllllllllllllly good.
Take out the "RV would set a precedent for NBA rentals to come to ISU" factor (or whatever chance of RV for more than one year), and BDJ is definitely an upgrade for this season.
A guard court of Morris, BDJ, Naz Long, and Matt Thomas is frankly terrifying come March and April to any other team. Let's hope they play that way.
