I'm not sure what Mittelstadt has to do with Jost... but on that train, it was obvious that Mittelstadt was mismanaged by Buffalo from the beginning. He was a project that they rushed based upon wanting to get rid of ROR and a great WJC. That said, his main issue, isn't all that dissimilar to Jost. He's not a good enough skater at the NHL level. Mittelstadt has a lot better set of offensive skills, but can't skate himself into the right areas. Now, Buffalo may have finally made the right choice with him and put him in the AHL to apply his game for a while. The last couple months of the season, he was one of the best players in the AHL. If he can continue that, and drop 10 pounds, there might still be a NHL player there. Still more upside than Jost. All that said, Mittelstadt busting will still cost a scout his job.
Every year since Jost has been here, he has been penciled in as a 2nd line player to begin the season. Each year he loses that spots because he isn't capable of it. He's a soft 3rd/4th line player at this point. He works hard, plays solid defense, and is genuinely a good kid... but he isn't a top 6 capable player. It is hard to be a top 6 player in the NHL and sometimes top 10 picks bust like this... but even if he has a career as a solid 3rd liner... for his position, he's a bust.
