I'll say this... while I don't think any draft trade chart is the "gospel" in league circles, I could pick fights with any of them...
Like if I look at the OTC chart, while they clearly value mid-round picks higher than say the JJ value chart, they also seemingly value everything across the board higher, at the expense of first rounders.
For example... if you look at OTC, if I wanted pick #65, which is top of the third round, the trade chart says all I would have to give up to get it is roughly 4 7th round picks. Do you think any team in the league would accept 4 7th round picks for a 3rd rounder, straight up? I don't.
And that's not a pick swap either. That's not a third for a third + 4 7th rounders. That's just 4 7th round picks for a top-end 3rd rounder. I don't think there's a single team in the league that does that deal. 7th round picks, across the board, are almost entirely throwaways. They're no more or less likely to "hit" than an UDFA is. The Ravens basically don't have a 7th round pick worth a shit in franchise history, which spans 25 years.
I understand how some sites may value 1st rounders more and devalue mid-rounders, but the reality is that, when I look at OTC's chart, for example, I think they've gone too far the other spectrum. They put way too much value in 6th and 7th rounders, and probably not enough up front.
So if I'm valuing this trade... I got one site telling me they got a mid-first rounder, and other sites telling me they got mid-second rounder. I would personally just agree to split the difference, meaning they got a late first round grade. Basically the 3 and the 4 they got are offset by the 2nd they lost. I think that's a reasonable assessment.
Which puts us about where a lot of us were expecting all year. Not going to get a top 20 pick straight up for him, happy to get a first rounder at all.
