... start the new season strong, with all of their players fully energized and ready to go. 

Unfortunately that's not always the case, as injuries and other absences can derail a team from playing at their maximum potential. 

With that in mind, here's my ranking of the top 15 players who may be unavailable for the 2010-2011 season opener in order of the impact their loss could have. 

Note: Most of the players on this list will miss time due to injury, and their rehibiliation period is a mere estimate. I also didn't include players who are projected to miss time well into the regular season.
