How many previous year 3 breakouts put up relatively solid age 18 and 19 seasons then plateaud as an amateur age 20 and 21 and did nothing as a pro age 22 and 23.
I will also add that I'm at a loss for breakout WRs that got playing time before their breakout and did so little with it in terms of targets. Not saying it doesn't exist in modern NFL history, but I couldn't find anyone that qualified from the top 150 current dynasty WR rankings. That's not to say that nobody has ever posted a worse target rate than Edwards in his first two seasons @ 5.8% & 7.3%, but the company isn't great.
He has JJAW beat (4.5% & 5.7% -- small sample size).
He also has Miles Boykin beat ( 5.2% & 6.1% -- small sample size)
The verdict is still out on Peoples-Jones, but kind of similar in terms of high productivity with the balls that get thrown to him, but doesn't get many targets ( 7.5% & 8.3%). I think of DPJ as more of a home run hitter, whereas I always thought Edwards had some potential to have decent volume moving the chains and as a redzone target. Perhaps I've been thinking of Edwards wrong, and his future is more of a one-dimensional deep ball specialist.
I thought maybe Corey Davis, but no, he's been at 12.6%, 12.8%, 9.7%, 12.8% in TEN, 13.1% w/ NYJ. He had an injury plagued year 1 & 2, but plenty of optimism. Dynasty value plummeted year 3, before his mini-breakout in Year 4 that got him his Jets contract.
Different kind of WR, but any comparisons to Lockett's breakout? Nope. Lockett was solidly above 10% in the early years, and actually plummeted to 7.7% in his breakout as a homerun hitter, before becoming a heavily targeted fixture in the offense.
With all that said, I have no problem with Edwards as a late round flier. He passes the eyeball test catching the ball and running with the ball, it's just everything up until that. I don't think we can count on Mariota chucking it up and letting him win the ball, as I begged from Carr. Maybe they can at least manufacture some RAC touches for him.
