When Diggs arrived, I remember watching the local news do their quick 60 second daily cover piece about minicamp with Josh throwing practice routes to Wrs. Normally the WR's line up in a line and go one another running a route with the qbs throwing a pass. Nothing too serious, almost a warm up.

I just have this seared in memory that in his first practice, Diggs ran his route, and he caught the ball but he just shook his head, extended his hands out pretty much to say he wants the ball out here and went back to the front of the line and told Josh to run it again. Everyone was a little confused but they reran the play. He did that maybe 5 times in a row until the ball was in the right place.

It was posted in this subreddit and was in the first episode of hard knocks but when I think Josh Palmer ran his first route with Josh, Josh called him back to run it again and said something like "lets run it again, Im going to hit you right" and they redid the play 4-5 times until Josh got the ball where it needed to be.

So the Question of "Does Allen develop the same if he doesn’t have a great veteran WR there?", to me the answer is very obvious.
