it's all valid for discussion. However, and you know more about knees than any of us so I think you will agree, the chance of a younger Dyess making a full recovery from a fluke blown knee accident was far greater than the older Houston recovering from a congenital proclivity for early cartilage loss resulting in deficient cartilage in both knees.
Well, it's tough to say. I'm not a knee doctor but I play one on UK!
But looking at the evidence, maybe the likelihood of Dice blowing his knee is greater than Houston's because he did it twice, the second on a fairly innocuous play.
As for Houston having a genetic proclivity for shytty knees, maybe that's true. Some people have better architecture than others. More likely though, he injured it like most players do, and just aggravated it for seasons when he should have gotten surgery.
In a strange way, blowing your knee is better than the slow-death of cartilage injury.

My cousin broke her foot walking on uneven terrain 6 weeks ago. If she had stepped 6 inches to the left she would have been fine. I believe catastrophic knee injuries are frequently like that. There is also the school of thought: It was bound to happen sooner or later. That reminds me of Shaun Livingston.
