At the risk of opening myself up for ridicule, I wonder if his playing style might be somewhat to blame for his injuries so far. I'm aware that Dortmund's medical team look they've been assembled from an abattoir but when you watch his flat footed running style and the way he crashes to the ground when going for aerial challenges, I can't help but think that it looks like an awful lot of pressure to put on your body, especially for someone that size.
For any basketball fans, the story of Derrick Rose should be familiar. You can go back and watch highlights of him when he was younger and, as well as being amazed at his insane athleticism, you can see the way he used to land so heavily after every dunk. Then his knees exploded and he was never the same player.
To bring it a little closer to home, both Vinnie and Micah were similar in terms of how they looked like they'd go all in for the ball with little regard for their landing or how they'd often put their body in similar stressful situations.
If that is true then it's a case of correcting some bad habits through repetition and committing new ones to muscle memory. Sounds complicated but it's similar to how Phil has done loads of work on his running technique with a specialist.
Hopefully, though, it's just a case of Dortmund doing Dortmund things because that would be way more straight forward. Plus, his manic style is part of what makes him so good to watch. His running style makes him look like something that crawled out of a well in an old Japanese horror movie.
Either way, I'm not concerned, just an observation.
