i dont know how much of a debate you're going to get out of this. most smart trainers work with a skill rotation in mind. usually 3-4 skills (though i train C/PF so i'm pretty sure there are more for outside shooters.)
(...)
more of a debate would occur in terms of what needs to be trained for each position. i know C/PF there is a debate on how effective shotblocking is. i'm of the belief that the skill is useless and work towards slowly making my big men into small forwards by replacing SB training with driving, jump shooting, and passing.
Thank you for your reply. I slightly disagree, but only in terms of how far the discussion/issue goes.
Yes, most smart trainers train 3-4 skills to e.g. a Center. But that is not what I call Multiskill. I would call it (like you do) "smart" or necessary. And I typify these players to be balanced. Not multiskilled. This is where I exactly find the discussion to be too limited.
And the debate about what skills are needed is in spite to a true Multiskill-debate already ongoing - and another issue in my view.
