So, back to the subject at hand.
Sprong is continually labeled as one-dimensional. However, I think this concept needs to be expanded.
Yes, his overwhelming skill seems to be his shot and his singular mindset to put a puck into the net.
However, we've seen other sides of him at times...I remember seeing the video of him still on the Penguins while on Malkin's line, and he gave Malkin a beautiful pass. I remember some other pretty good passes here and there. So he's got the potential for vision and passing in general.
I also remember him backchecking hard and taking a puck away. He's got the potential for defense, if not for relentlessness on the PK, at least backcheck pressure...and tying a stick up can absolutely be taught.
We've seen some recent videos here where his skating and puck handling is pretty damn solid.
I personally think the biggest issue is his blinders. Unless he's in a situation where it's very obvious he doesn't have an opportunity for a good shot, he's going to just take that shot. He needs to be able to think a bit more variably, and get to a point where he knows he's always got other options. Get to a point where he stops thinking just shoot, and instead "what options do I have?"
I still feel this can be taught...to some degree. I think he can get to a point where he's not a defensive liability, and has the potential to make plays, etc. Part of this is also having teammates that he can rely on, that he knows are going to work to get to soft spots or be where he can help create a good scoring chance. IMO, he needs to NOT be on the 4th line. He needs to be put with teammates that have some 2-way skill, and that are a bit more dynamic to give him the confidence he needs to try those plays.
