In 2012, IIRC, the same "read" by the WR and QB was mentioned. ie Bell would read the D and so would Martinez. They would then make the "same" read without having to audible to it so as to not let the D be aware that play has changed. It appears that Beck is trying to simplify the reads so the guys are actually on the same page. To many times the previous years, balls were launched into space with no apparent receivers. This was a "busted" read by the QB or WR. Martinez reads a go route and receiver reads the D and decides to sit down on the route. Appears Beck is trying to simplify the verbiage ie get plays in quicker and simplify the way guys "key" or "read" the D to "mentally audible" into the same routes.
