Could be a combination of poor routes from the receivers, and I think Martinez hesitated a full second too much on that play.
What I'm taking from this so far is that Taylor's running can open up the passing game - we see receivers running free in the middle of the field on occasion - and that we have to rely on that for our throws. If you see the tight outs Coffman is throwing, those throws in traffic where the receiver is covered, are lower percentages for us.
Of course as I'm writing this Taylor hits Paul in traffic and we are running a no huddle.
The throws Coffman is throwing are lower percentage for everyone... But i get your point.
