It makes me think of the Carlos Correa contract situation where you had two contracts fall through because they found I want to say they called it pre arthritis in the ankle he broke in the minors. So far it hasn't slowed him down and I feel like with baseball you can get away more with having bad knees/ankles but I could see how a defensive end it would be much more problematic.

Found a comment from his Dr. about the situation...

Maxx Crosby's surgeon speaks out
As confusion reigns regarding Maxx Crosby's prognosis, the surgeon who performed his meniscus repair spoke out.

“Maxx Crosby is doing very well in the early part of his rehab and recovery from surgery to treat a significant meniscus tear and the related stress injury to the bone and cartilage in his knee," Dr. Neal ElAttrache told ESPN. "He is certainly on track in his planned program….he feels very well and is already much improved compared to before surgery."

ElAttrache added that the timing of the trade proved to be a particularly difficult obstacle.

“We truly respect the work of the Ravens staff with Maxx regarding the contract physical exam," ElAttrache said. "We also understand the challenge the staff faces when tasked to provide a future risk assessment based on an evaluation early in the recovery process. This is especially challenging when dealing with an elite player like Maxx considering the level of commitment necessary for a team to obtain him. The timing of this assessment is unfortunate because the apparent risk will lessen as his recovery progresses and his return to performance over the next few months becomes clear."
