You guys forgot one big important thing. Center is very close to the basket so he won't need jump shot/jump range/driving too much. Engine values inside skills on big men much much more. Also, high inside skills may help a guard but if he's balanced. What's the use of high inside scoring when a guard has low driving and handling? He can't even get to the rim to utilize his high IS. I'm sure this training plan will backfire but if anyone wants to try it out - good luck. :)
I'm not sure what exactly you're replying to, but if it's my initial roster idea, I'm aware not all skills that are there are needed, the example roster was to show how much skills you can get for a certain salary. To make training faster, skills can be of lower levels, but to find out a proper training schedule was to be the next step. Also, the bigs in my plan do have IS, and my guards do have DR/HA, so they can utilize IS.
I know training will be harder, but it could be worth it if you can cut salaries in half at the end right?
