Go buy yourself a $10k salary SF, who has lowish handling/IS, and just train the both of these guys in Driving for forwards for the rest of the year, throw in a couple of weeks of passing for the SG. ..... You need to get this guy 4-5 pops in driving before he will really start to dominate. but dont stop there, keep going, more pops in driving. more more more!
Essentially, his Marvelous JS rating is wasted without higher driving.
What not to do. Do NOT train this guy in Jump shot. if i see him get trained in JS, i will personally come over and swat you in the head. :)
and lastly, I would definately train stamina and Free Throw at least once each this year. Nothing worse than a low stamina, low FT, high JS, SG.
