Hey there, Targess and welcome to BB. Firstly, all of the guys who have commented in this thread know what they're talking about and have a wealth of experience so listen carefully to all that is said. Secondly, I was in your position this time last season when I acquired a 6'0" MVP potential SG (Johnny Dogan). I spent the entire season training pressure as Yoda suggested (by the way, he's my mentor and very knowledgable). I watched this fairly ineffective SG (Dogan) go from not hitting a shot and being unable to defend Stevie Wonder on a good day, to defensively stopping $20k guards. How? I hammered his OD (Pressure) until he (and my other trainee, Rodriguez) were at Sensational OD. Now, with the elastic effect kicking in I expect Dogan (who was popping every two weeks like clockwork) to start to help out the team offensively as I have switched training to JR to capitalise on the elastic effect. Lastly, as Yoda suggested, I play Dogan and Rodriguez for the required 48 minutes in position and then have them back-up in the second game. If things go pear-shaped, you can always utilise the Scrimmages to ensure training is maintained.
If you have any questions about anything regarding their training ask the guys using this thread. I'm always happy to answer any questions through BB as well. Good luck.
PS. You suck! LOL That starting group of rookies is awesome for a new team. Get your training program set up now for the next few seasons, get that level 4/5 trainer (I have a Level 5) and start building your team around your future stars.
