Think the NBA can change that. NBA teams as we know invest a lot more time and staff in the physical conditioning of players.
Physical conditioning cannot change frame. Evans can kill himself all day long on the weights and eat an entire cow every night and he is never going to put on 50 pounds of muscle (which I'm pretty sure would put him around 230), notwithstanding that it would probably slow him down. Also, you can lead a horse to water but you can't make it drink. If Motiejunas didn't and doesn't have the drive now, why would that change now making a guaranteed $5 million?
