I'm more concerned that the current environment is not the best for a guy that young. When you have some veteran guys playing with what looks like apathy and lack of pride when they're getting dominated it's just not something you'd love seeing your top young players exposed to. It's not something they can't get over once the team is healthy/better built and coached with better systems and a winning philosophy, but it adds to the frustration of these horrendous losses.
But I'm not concerned about his development trajectory. Strome is not a reliable line partner and clearly doesn't have much chemistry with Leo and it doesn't help that Rico has been cold lately.
