When was the last time the top 4 rookie RBs all performed well?! We could redraft them for dynasty now and a good argument could be made for any one of them to be taken first.
2017 was close, they did not quite perform as well as this group but close. What is very similar about the 2020 and 2017 RB class is two other things.
Both drafts saw later rookie RB's hit and hit big. Hunt and Kamara in 2017, Gibson and Robinson in 2020. Some other hits from 2017 later but none that got in top of the group discussion.
The other big thing that is similar relates to your last line. After the 2017 season opinions were pretty split on who was the top RB from that draft but almost no one was saying CMC. I'm ashamed to say I think I had him ranked 6th after his rookie season about this time of year and that was not crazy to put him behind Kamara, Mixon, Fournette, Cook and Hunt at that time. (I'd just add I did buy into Norv's increased usage talk around August preceding CMC's rookie season but I mean at about this time in 2018 I put CMC 6th-I'll own that). But I recall I struggled with ranking them, was not easy calls.
You say redrafting the 2020 RB's would lead to a good argument and I can't even agree with myself. In fact it did remind me of trying to sort them out after 2017, just deep and talented and learning from CMC to some extent not trying to get to carried away with just how they did this past season.
Swift- top 10 RB after bye week. Dan Campbell and Saints system might be a boon, already talking of putting him in slot. He's got Kamara upside.
Akers- could be McVay's new Gurley
Taylor-I assume he'd win 1.1 voting right now among consensus.
Dobbins-closed year strong, shook Ingram
Robinson-best one for most of the season, gets Trevor.
CEH-he was my 1.1 in drafts, remembering how unspectacular CMC looked his rookie season might be a good lesson for people to remember here.
I own all of them except Akers and Taylor and I have hard time ranking them. I think it's easier for me to say who I have last then who I have first.
IMO the 2020 RB class is on par with how good the 2017 RB class looked after year one(keeping in mind players like Conner were not held in any regard). I would also say the 2020 WR class was on par with the 2014 WR class after year one. This is why I've said a few times on these boards we just witnessed the best rookie class in at least the almost 10 years I've been playing dynasty. If you loaded up on #1 picks and high to mid seconds last year I bet your team is looking pretty good.
