The issue with JR IMHO is that it really only affects three-point shots. If you are an outside team, you definitely need JR because 3 point shots are nearly 50% of shots taken by a outside SG. Somewhere between 85-90% of outside sg shots are either jump shots or 3 pointers so obviously JS and JR are building blocks of an outside guard. After that it gets a little murky and depends on what type of team you are building and what secondary offense you want to use. You can make arguments about needing
DR - I personally love DR on everyone. While outside offenses don't create alot of driving shots, high DR can help an outside team in a couple ways. We had two guards in my first term as U21 manager who had about the same JS/JR but one had much better DR and IMHO performed better and was able to start in many different tactics.
1) "Allows the player to create his own shot without a good pass from a teammate." If you decide to have lower HA/PA on your team, higher DR helps you create shots if you have bad passing.
2) "Better driving creates shots more often and creates better shots on average." If this guy is suppose to be your best scorer, you want him shooting the most and shooting the best shots possible.
3) Gives you flexibility to play other offenses. DR is especially important for the Isos. If you want to set up your outside stud as your patient shooter, my second point is important as well.
HA/PA -I usually group HA/PA together. If you use alot of 1v1 to put DR on your guy (and increase your HA), you probably will have to lower the amount of PA and vice versa.
1) "Important against... good perimeter defense. Teams with good handling will have more success at creating quality shot opportunities." So you want to beat OD?
2) "[PA] Helps to create good shots (and get assists)." I think PA is especially important if you want to play Princeton. Better passing, leads to assisted shots. On the NT level, the USA has had good passing on pretty much all of our guards the last couple of seasons and I think it helped us a little more to over come high OD than the Chinese method of punting PA. At the same time, do you want your outside stud passing the ball or do you want him to shoot?
OD- I think everyone pretty much agrees OD is the most important guard skill in BB. The problem is that it is the second most expensive skill in the SG salary formula after JR and takes up significantly more cap and salary room than the PG formula. Like Manon said, having build between the PG/SG positions helps but you might also consider getting a little creative and training alot ID and defensive switching to SF so that you can train less OD and more of the other outside skills.
