Purdue - IU Blarge

[Kansas Ref]

I had a charge when I saw it live last night on TV. From the perspective of one who only does NF level games, I have indeed been party to rare instances when one official called a block and the other a charge; however, we conferenced and resolved it as either but never issued a "double foul". Furthermore, as I recall our own conferences were quite brief as compared to the lengthy process of "locating dance partners" that occurred in the case under study.

Also, this is my first time seeing a half-way block [i.e., one fist up and hand on hip] by the L. Is this some new mechanic that those of you who ref college are doing now?
