While Jakob may be able to get to a point where he is minimally tough enough, it is usually a big mistake to try to change basic personality.
I think Jakob will improve his toughness to a reasonable level.
More importantly, however, is that he demonstrate his proven potential in games as a very high level 3 point shooter. To this point, fans who don't know him have only seen his poor game performance, and none of his rather remarkably consistent long range shooting on the practice floor. I think he has the character to get there.
