https://www.profootballfocus.com/blog/2013/05/29/examining-pressure-qb-play/ Take a look at the site for all of the data. Brady is #2 in the league against edge pressure, but worst in the league when the center gives up pressure.
I'll bet Sanchez RT struggles are because he looks so hard at pressure coming from that vector due to the Wayne Hunter fiasco in 2011.
Some pretty good info. I noticed that Tannehill did pretty well last year under pressure. Let's see if he can replicate it this year now that teams have a yr of tape on him.
