i have a very important question about cross-training
for example if i start training an 18 old player on 1vs1 for 1 year is that true that it will accelerate his main skills
for example lets assume a PG his main skills OD , PA , DR , JP.Ball-handling
Of course when you train 1 on 1 it will increase DR,JP, Ball-handling but how fast it will raise his OD and PA.for the next years
I hope to have an answer because people are talking all kind of things.
thanks a lot
