Doesn't it seem like the same teams year after year are getting hit with devastating injuries. For example take the Patriots, Chiefs, Packers, Steelers. These 3 teams always have suffered so many crucial injuries on defense and offense.
Then you have a team like the SF 49ers who have been incredibly injury free for most of the past 3 years under Harbaugh. The 49ers defense had all 11 starters play all 16 games in 2011. In 2012 their starting defensive lineup only missed a few games and was healthy for the playoffs. In 2013 they are the healthiest team in the NFL on defense, offense, offensive line.
The Packers starters were dropping like flies during the game. Chiefs lost 4 or 5 starters on saturday. The Patriots receivers cannot stay on the field for more than a few games. The Steelers have lost 2-3 O linemen the past 3 years. I won't even get started the injuries on defense for the Pats, Steelers, Packers.
How does something like that keep happening? I do not believe it is pure luck, not for 3 straight years. Same teams are injury prone and others barely have any injuries.
Do the 49ers have a superior training staff? Do they simply have better conditioned athletes?
