I would advise you to rotate skills, unless one of the skills are far behind. As for the first guy, I think you could make a good PF or decent C out of him, but you would need to get his HA up to inept. If you want him to be able to defend against well-rounded PFs, his OD should be at 6. His stamina may also be a problem, but you can just train that if he gets injured or when he is 22+.
The second guy could be a nicer PF/C combo with a bit more OD/HA/DR/PA. I would try to get them to 6/6/8/7. These are loose, short-term goals to shoot for, and with their potential, you can make them higher.
