Good start for your build. If your str isn't soft capped at 48 go ahead and finish it off. Auto train carrying to 15-16 and get your speed and stamina to 20-25. By then your carrying should be over 15 from auto training so I'd go ahead and get that to 25 or so. Then you can start auto training vision and confidence.
After that you have several good options to go.
1) Hit the 61 cap for str
2) get speed and agil in to the 30s
3) get carrying in the 30s
4) vision/confidence 20+
5) grab a few SAs
6) if you're running low on energy you can work on stamina
The path is for your to decide. Watch closely how your HB is performing and figure out what you think will make him better. You have a good start with your HB (capping str asap for powerbacks is pro and smart) so he should do well. Good luck.
