That the NFL would try this out to try to identify injury mitigation practices is not something to reject out of hand.
It might tell them something; it might lead to long overdue improvements in helmet technology, for instance. Or it might be just another "big data" experiment that nobody can figure out how to parse.
In the mean time, the idea that this data will be piped into the broadcast booth before anybody has tired to figure out what it means is ludicrous. The idea that we might hear some announcer say, "That hit by "x" player registered "y" PSI on the receivers left shoulder pad sensor is the highest recorded so far this season!" only pollutes the understanding of the game.
That this data might eventually be used to enforce "hit to the head" penalties called by the booth official should not be ruled out, for good or ill.
