There was an argument long ago about whether jump shot should have FT shooting as a secondary training skill (then you wouldn't have the guy with the awesome jumper, but can't him a FT), but many people argued that they were totally separate skills (myself not among them).
Yeah, but you're not good at FT's just cause you're good at Jump shots, just like you're not good at jump shots just cause you can hit free throws.You still need to practice both. In real life, and in Buzzerbeater this is the case.
