I don't think more training is going to help. His body is probably in great shape. I think that some players have more balance, vision, prioperception, reactions/reflexes, or something which keeps them "lucky" despite many hits. Basically they get hit "squarely" less often and therefore are injured less. Goodwin just seems "unlucky" and in ways that are not explained by toughness alone. I think he just doesn't "slip" hits well enough... So he probably will not make it as a consistent NFL player. Too bad because he made some nice catches.
