The issue isn’t his lungs, it’s that his knee is absolutely shot. Already had 4 surgeries on it and had part of the meniscus removed which has seemingly led to muscle injuries as well. Real shame as he looked like he could be one of the best.He’s got worse lungs than Geri him
Hopefully he can fully recover and have a good career but that much work on his knee at such a young age doesn’t look good.
