Let's look at the players on IR and see what types of injuries we've got:

Betts - knee (if I remember right he got rolled up on, not much you can do to prevent that)

Cooley - ankle (broken bone, again not much you can do to prevent that)

Portis - concussion (see above)

Samuels - neck (pre-existing condition)

Thomas - triceps tear (preventable?)

Brennan - hamstring

Horton - toe (ligament damage)

Rinehart - broken leg

Eddie Williams - broken leg

Jeremy Jarmon - knee

Honestly I'm not seeing many injuries here where you could say it's definitely a training issue.
