Injury plague – bad luck or bad management?

There was an interesting bit of analysis on Dallas in the Football Outsiders Prospectus for 2008.

We have (had?) the lowest injury rate in the NFL for the last 5 years to 2007 -by a considerable margin.  We showed an average 3.6 "adjusted games lost" vs 8.2 for Houston in 2nd place.  No other team was under 10.   So we are way out in front. 

They noted there is an element of luck, but said over 5 years this should even out.  They attributed to this strong performance to Joe Juraszek and how he works on "functional fitness" using trampolines, exercise balls etc and not just old fashioned lifting and sprints – as well as to the medical staff. 

They also noted that when we did get injuries, they tended to not keep our players out for long - again attributed to JJ.  They did say more teams in the league are now following these approaches. 

Of course no sooner do they print that analysis and we get hit with:

Kosier, RW1, Anderson, Watkins, Spencer, Austin, Hurd, Scandrick, Newman, McBriar, Felix, Romo,....  

What really bothers me though is the number of re-injuries:

Kosier – returns and re-injured

RW1 – returns and re-breaks the hard

Newman – plays when clearly injured and has to have surgery

Hurd – returns and re-injured and out for season

Watkins – been in and out

Scandrick – been in and out

Austin – been in and out

Witten – gets cleared to rejoin the game and turns out he has a fractured rib!  Lucky he had the good sense to stay out.

And to top it all, Felix gets hurt while re-habbing an unrelated injury!

What the heck is happening?  Is this Karma catching up with us big time?  I know Juraszek is still around. Any insiders know if anything significant has changed with his training approach or the team’s  medical staff?
