Road To Glory Pure Runner Archetype

When I make a pure runner qb archetype the game says you can get platinum shifty as an ability. The pure runner maxes out at 89 or 90 speed which makes 0 sense and means you can never get platinum shifty on your qb. Is it false advertising. If I make a pure runner shouldn’t he have 95+ speed and get all those abilities platinum. The pure runner is slower speed than backfield creator. Ea that makes 0 sense. Someone help if I am doing it wrong. But I want platinum shifty but it’s physically impossible to obtain.
