First Down Measurements

Came up when Turner Coxe stood Perry up deep in their end in first half short of the first down, yet the refs were magically able to tell he had clearly (not) made the line to gain without even a glance at the sticks, nor a measurement.
Has anyone else noticed how rarely the chains are brought out this year for a first down measurement?
I can barely think of more than a couple chain measurements all season in SMU games.
This is not unique to SMU as it has the same in other college games as well as the NFL.
Anyone with any insight to this?
