I don't think there is. I think what we have here is a classic case of piling on. Things went against him the last 1.5 years with form and injuries, so the theory was that he must've not been that good. I don't think that was the case.
You are right that he was highly touted coming out of minor hockey, they were saying he'd be the next Eichel. He had a bad season last season, but just about every player on that team was bad last season, they underachieved bigly. So his stock was already dropping coming into this season, and then he got injured a few games into the season, which dropped his stock even more. He's only going to have half a draft season, that clearly doesn't help draft stock. Players usually find their way up the draft boards pretty slowly. If you drop 20-30 spots in 4 months because you aren't playing, it usually takes another 4 months to be able to go back up 20-30 spots, regardless of the reason you fell those spots.
It is true that he's not going to be the obvious 1C he was touted as a few years ago, but I don't see a drop in talent. The kid is putting up stats in the USHL that like 5 players have since 2000. He's very talented hockey player, and flaws in draft rankings shouldn't reflect poorly on what Wise is doing. As for his shot, I don't think its bad, I don't think he uses it enough. If you look at many of the goals he's scored this season and even last season, a number are outside shots. He can shoot the puck, but he's a pass-first player who doesn't shoot enough, so he's just not a big goal scorer right now.
