I think with Diggs, he's been nursing some dings and then showed up on injury report with a foot injury, he might not be running as many routes in practice.
But the timing was there, the ball and Diggs were perfectly in the right place at the right time, he just wasn't able to close the deal.
I've heard it said that catching a ball starts with the feet?
This is where I am. Shut up and play better.
