My personal thoughts are that Roy Williams is still having trouble running the correct routes. A lot of the successful connections between he and Romo have been where Romo can see Roy's path prior to throwing the football (like the post pattern against the Bucs), but the quick breaks and hot routes have been hit and miss. The good news is that this is correctable, but the question is "when" this correction will occur and when these two can get in sync.
I am not standing up for Roy, because it has certainly been long enough that he and Tony should be in tune by now, but I am saying that if they get in tune come November and December, then Roy and Miles could prove to be a very scary combo at the wide-out position.
Just one member's opinion.
