He has a good amount of skill points already, and since he's only P. Allstar I'd start training him inside for about 2 seasons. You still have plenty of time afterwards to cap him, but he'll be a much more valuable player, both money wise and skill wise. I think you can get IS and ID to around 10. Then switch to 1v1 to get DR/HA up, because if HA is more than 3 points behind PA/OD it will slow those down due to elastic effect. I'd train it to around 11 and then finish off with JR/OD/PA as you see fit, maybe a bit of JS to bring it up to 12-14.
