The thing I noticed on the double moves is that when the receiver makes the first move (or the out move) Roby is breaking towards the line instead of flattening out at that point. Therefore, when the received makes his second move (back down field) Roby is heading in the opposite direction and therefore causes separation. This is not first game where Roby has had this problem. I've seen it numerous other games as well.
This can be fixed with a little film study and practice. The idea here is to respect the double move and to not break on the ball until it leaves the QB's hand. By breaking towards the line on the first move, you will get an int on occasion, but when the Off coach starts seeing this, they will run the out and up double move to free up the recieve.
