It doesn't surprise me to see so many rookies on this list - because the rookie hype happens every year. But I can't understand why a first year player is preferred to a second or third year player.
Because - while it depends on the league size, scoring rules, lineup formats, etc. - in the "back half of redrafts" I'm generally swinging for the fences. I'd almost always rather grab a guy with a small chance of making a big impact than one with a big chance of making a small impact, considering the latter are generally available, for free, all season on the waiver wire.
And while one can reasonably argue about how efficient the NFL is in many areas ... it is a ruthlessly efficient machine at identifying elite talent. If you have "it", it shows up early. And if you don't, well, that shows up early, too.
Let's take WRs and TEs as an example.
Here's a list from PFR of every 1st- and 2nd-year WR and TE in the last two decades who has put up 60+ receptions for 800+ yards and 6+ TDs - not necessarily elite production, but certainly enough to indicate that a player might have "it".
It's not a big list - there are only 50 such seasons in the past 20 years. But here's what you'll notice:
Almost every fantasy difference-maker from the last 20 years appears on this list. Among the top 16 names alone you'll find Bruce, Gordon, Jeffery, Moss, Fitz, AJG, Megatron, Gronk, Marshall, and Graham. Further down there's Julio, Andre, Gates, T.O., Witten, Dez, and so on. Compile a list of pass-catchers you've taken in the first two rounds of redrafts over the last decade, and almost every name will be on here somewhere. It's basically the
Little Black Book of Future Fantasy Studs.
If, in the 12th round, I have my choice of a third-year WR who has shown flashes but hasn't put up significant numbers, or a highly-touted, highly-drafted rookie in a decent situation, I'm taking the rook probably 8 times out of 10. The rookie has some chance of being a stud right out of the gate, while history tells me that the third-year guy has relatively little ... because, while there are exceptions, if he had the kind of next-level talent that was going to help win games in the NFL, his coaches and teammates almost certainly would have gotten the ball in his hands more in his first two seasons to help them win those games.
