Research studies on health and safety have offered differing opinions on practice regimens. Now even NFL teams are taking different points of view when it comes to practice contact.
For instance, two NFL teams -- the Kansas City Chiefs and the Carolina Panthers -- are using practice routines that are 180 degrees apart, according to The Associated Press.
On one hand, the Chiefs are doing most of their heavy contact drills early in training camp.
The change has left all Chiefs players with a different mindset.
On the other hand, the Carolina Panthers are de-emphasizing hitting and want more form tackling. Coach Ron Rivera wants players wrapped up, not tackled, during training camp.
