Still, it hurts them if he misses any significant time. They're basically 6 deep and trash behind that. Bogut, Igudola, Lee, and Curry all have significant injury histories. Iggy might be out awhile, Barnes missed some time earlier, Curry has been hurt twice already (ankle & concussion) and it's been Igudola who has basically kept the team rolling while Curry was out. They have no more than a 2 game lead for a playoff spot over Houston, Minnesota, Memphis, Phoenix, New Orleans, Denver and the Lakers.
If they start losing games because of injuries, the healthy guys will have to play more and end up getting worn out (like Portland last year) and possibly struggle with more injuries. It can go south in a hurry.
If they lose Curry it would be bad, bad, bad for them. No matter what the Jazz record ends up being, if the GSW pick is in the top three, DL deserves GM of the year award.
