That sounds like a shitload of work to look up if you're narrowing it down to solely first round picks. It seems like a meaningless distinction at any rate, as guys develop at different rates regardless of their draft position.
All I know is that it's generally acknowledged that WRs can take three to four years to break out. If they don't break out by year four, you can usually chalk them up as busts. It was the 2014 draft that kind of screwed up everyone's expectations for rookie receivers, as that one had several guys who were year one stars, which is rare.
You also have to account for the fact that it's not as if Coleman was garbage. When he played and got a decent number of targets, he typically had good games. He just missed a ton of time with injuries and had to deal with very inconsistent targets and QB accuracy when he did play. There's a big difference between a guy who flashes talent and has a bunch of good games his first two years and a guy like Mike Williams who had 95 yards his rookie year (and even him I think it would be foolish to give up on already).
