They call it when receivers do not have the ball and get TARGETED.
The rules are so open that even the refs have problems with them.
Bingo! in the name of safety and "concussions" spawned by the MSM, this rule was enacted. Yes, there have been some serious injuries and the reaction by the NFL and NCAA is overkill.
We are witnessing the glorification of the NFL and the NCAA has started to follow suit. I reject it whole-heartedly.
To your observation that somehow the lack of a targeting call against Bama vectored the game in Bama's favor and an ultimate victory - I disagree. Bama was the better team last Saturday. tAm played well in the second qtr though and Bama looked asleep at the wheel for that period. In Saban fashion, the team adjusted and responded in the second half. If there was a penalty that pushed a shift in momentum, it was the hands to the facemask of Hurts in the 3rd.
Having said that, I give respect to the Aggies. Sumlin has made them a great team and a true contender in the SEC.
