1 Position Training
I thought I'd steal this from the NZ off-site, it's a tremendous guide on how to train if you have 2 or 3 young guys (21 and younger usually) at a single position that can get focused attention. They will become monsters in no time if you follow this.
I think if you manage to give training to three players every week 1-position training is not only better for the single player, but also comparably good for your entire team.
Ok: how do we make three players play 48 minutes at PG?
So we have P1, P2 and P3.
Game 1
make sure that:
1) P1 is set as Starter, Backup and Reserve at PG.
2) you play Strictly Follow Depth Chart
3) you are dressing only 9 players.
4) every other non-starting player is in the depth chart as a sub for some position other than PG
5) do not play Full Court Press
6) If the game does not matter too much to you, avoid fast offenses (R&G, LI, PtB): they are, in my view the most effective, but they decrease the chance of your players' getting 48 minutes (lots of possessions = more fouls = more chance your player will foul out).
Game 2
Same as above with P2 in place of P1.
In addition, make sure that between first game and second game, P3 gets a few minutes (say 15-20) as a Shooting Guard.
The reason this is important is that if P3 fouls out in the third game you can still use his minutes as a SG and switch to *two* position training.
Game 3
This is your scrimmage.
Follow the same instructions of first game.
In this game however play Patient or Princeton.
Set "let them play" in the fouls setting.
There are typically only two reasons why your player will not get 48 minutes: i) injury ii) he fouls out.
If for some reason, one of your players does not get 48 minutes in a game switch back to 2-position training before the update.
If P3 happens to not get enough minutes, because he fouls out, if you've given him enough minutes as a SG during the week, you should still be covered (it's rare for players to foul out with less than 30 minutes of play, though it occasionally happens to some of the roughest guys).
If P1 or P2 do not get enough minutes, make sure that they get minutes at SG in later games (so you can, again, exploit 2-position training).
Remember: there is no 1-position training for Jump Shot or Rebounding. So these are ideal fall-back options if you fail to train your player in the skills you wanted to train him in.
