He had no IS, RB around 6-7, can't remember everything.
.365 3 point% isn't good if JR is 18. I have players with JR 10-13 shooting better percentage. It could also be affected by a player's mentality, some shoot more, some less ill-advised shots. It's probably not a good idea to prove something statistical through just one player.
I'm interested in your experiment and will do my own.
imho shooting percentages are a lot effected by team instead of individual skills. When i trained offense skills and mostly one trained player was on the court, the player nearly keep his shooting percentage, but start taking more shoot and the shooting percentage of the team sligthly increase over the season.
Also three point percentage of 4close to 40% is good in buzzerbeater, and mostly impacted by tactic, if you play mostly outside tactics you can reach this value but playing more often inside will lead to games where the team shoot 10-20% three and him getting those desperation shots.
Overall i also like the JS a little higher then Jr(~10%), but big differences on those two skills lead to bad performances for the skillsum.
