I'm curious to know how you know this stuff, but it's certainly interesting stuff. Here's where it's even more ridiculous that the league combines doctors' opinions PLUS the actions of other teams to decide if an injury is "career ending". Presumably any team could know this. Why couldn't it be the case that for a team like Portland, who is investing a lot of money in Miles, he just can't perform anywhere near to the worth of their contract (i.e., can't play heavy minutes if needed - that is, fulfill his contract) without destroying the knee, but for a team like Memphis he could? In that case, it seems fair to me to say that for Portland his knee is legitimately career (as a Portland Trailblazer)- ending, even if he goes on to play limited minutes on ten-day contracts for other teams. So even if another team signs him, Portland should get cap relief. I'm perfectly willing to allow that Portland should lose the cap space if independent doctors decide that the doctors that examined Miles were wrong to conclude that he couldn't pay SIGNIFICANT MINUTES without crippling damage. But this "ten games" stuff proves nothing.
Multiple cartilage injuries and surgeries. I have the same condition in my knees that Darius does. I blew out both my ACL and MCL and recovery from that injury was a cakewalk compared to the day-to-day pain I experience from bone-on-bone. All I'm trying to do is defer a complete knee replacement until the promise of artificial/regrown cartilage becomes a reality.
