Have to apologise for my irrationally overbearing previous post, was having a foul day at work, didn't mean to sound so confrontational.
Also frustrated at having similar arguments about Troy Menzel previously.
Yes, as various posters have pointed out, (with lots of reasearch) there are familial genetic links in some cases of structurally unsound joints resulting in ACL ruptures, as well as genetic links to weaknesses in connective tissue, I did not mean to suggest that there could not be a genetic cause to ACL ruptures.
What i meant to say is that Troy's knees can in no way be interpreted as being genetically linked to Daniels. And, based on such a small sample size of incidences, it is scientifically unsound to conclude that Troy is predisposed to any further injury.
It has been revealed that Troy's initial knee reco was due to an injury sustained through IMPACT, which does not point to a weakness in the knee necessarily, and could happen to anyone regardless of genetics.
This is an understandable point of concern initially, as any player who has had serious injury would need to be assessed carefully.
What irks me, somewhat, is pointing to the problems of his brother as evidence for not drafting him. I would like to see how many family members physicalities are assessed when drafting new players, and whether, if Daniel had the injuries, but wasn't well known, people would be as worried about Troy's knees as much. I doubt that on one previous, (and reportedly very strong and stable currently) knee problem, Troy's talents would be overlooked so easily.
I don't know that we can assume they have the same genetic flaws, it doesn't seem very sound to me. Unless we can grab some cheek scrapings off them and do a quick PCR. Better yet, lets do whole genome sequencing of every potential draftee to assess their natural endurance, power, structural qualiieis... It's getting close to about a thousand bucks a pop now anyway.
Yes, Daniels injuries were innocuous, and point to structural issues, Troy's injury was not, and does not necessarily. Indeed, rumours of a clean bill of health, and rumours of him sliding up the draft order suggest some medico's have assessed his issues, and given him a pass. Julian Feller certainly has.
Yes there is a familial disposition to some presentations of the injury, but I think it would take further research into this particular pair to assess whether there is actually a link between these two. There could be, but I wouldn't ignore him based on could be.
